DESCRIPTION FIG. 1 shows a layout of an optical system 10 for coupling light signals at very high rates. A laser light source 11 , such as a vertical cavity surface emitting laser (VCSEL) may emit light signals 12 which go through a transfer optical element 13 . From optical element 13 , light rays 14 may impinge on a core or face 15 of an optical fiber 16 which may be a multi-mode fiber. Rays 14 may propagate through fiber 16 and exit fiber 16 at core or face 17 as light rays or signals 18 . The light rays or signals 12 may be conditioned into light rays or signals 14 to make high speed transmission through optical fiber 16 or other like medium possible. Achieving, for instance, a ten gigahertz bit per second data rate in fiber 16 with an approximately 2000 megahertz kilometer bandwidth may require careful control of the intensity distribution of light 14 at fiber face 15 , i.e., a launch condition. An industry specification specifies a power distribution at the output fiber face sufficient to achieve a 2000 MHz-Km bandwidth-distance product in a 500 MHz-Km GI fiber. The Telecommunications Industry Association (TIA)/Electronic Industries Alliance (EIA)-492AAAB specification (hereafter “TIA specification”) effectively says that a 2000 MHz-Km bandwidth at 850 nm through 50/125-micron graded index multimode fiber can be achieved if at the end of the fiber the encircled flux within a radius of 4.5 microns is less than or equal to 30 percent of the total and the encircled flux within a radius of 19 microns is equal to or greater than 86 percent of the total encircled flux. An example of the fiber may be Corning's standard 50/125 multimode fiber which has a core radius of 25 microns and a cladding radius of 75 microns. The core and cladding indexes of refraction are 1.4948 and 1.4800, respectively. The wavelength is 850 nm. Various illustrative examples of the present invention may provide the appropriate distribution of power into fiber 16 to achieve the data rate performance of a 10 gigahertz bit per second operation at 850 nm that is compliant with the above-noted TIA specification. The power of light source 11 may be redistributed by optical element 13 from the center to the outskirts of the beam which is projected on to core 15 of fiber 16 . The velocities of the various modes of light are more diverse closer to the center of core 15 than the velocities of the modes of light closer to the perimeter of core 15 . Since the velocities of the modes of light near the circumference of core 15 are close together, a light pulse having its flux or power concentrated more towards the perimeter will come through fiber 16 tighter and more distinguished in shape. This closeness of velocities of the various modes makes possible for very high rates of data transmission. That is at least one reason for the outer concentration of the power of light signals in core 15 . Attaining a power distribution of light on the end face core 15 of fiber 16 may be tried with a conventional, well-corrected, aspheric transfer optics as an optical element 13 that is adjusted to the best focus. This kind of optics may not be sufficient because compliance with the TIA specification could be achieved only for a few special modes, such as mode 2 , 1 of a VCSEL as a light source 11 . Robust compliance for a wide range of modes, for instance, of a VCSEL, and with tolerance of lateral and axial misalignment of the projected light from the optical element to core 15 may be attained with an optical element 16 whose point-source distribution function or point spread function (PSF) at the fiber face of core 15 complies with the TIA specification. PSF refers to a distribution of light on the fiber core face from a point source. The point source may radiate light in a spherical manner but only a cone of the light is captured by the optical element. The outgoing light from the optical element may be converged to a point, for example, with a lens. However, the reality is that the light source is not actually a point, and that diffraction and aberration, among other imperfections, prevent the light from being focused as a point on the fiber face. Even if the source were a point, the diffraction and aberration of the transfer optics or optical element 16 would prevent the projection of a point of light on the fiber 16 end face. A well corrected optic would have distribution curve 19 , as shown in FIG. 2 , on the fiber 16 end face. However, curve 19 does not comply with the TIA specification needed to achieve the 10 gigahertz bit per second data rate in the 2000 MHz-Km multimode fiber using 850 nm light. In order to get the power or flux distribution needed by the specification, one may maintain an annular intensity profile on the fiber face after convolving the PSF with the finite light source aperture, apodizing the complex source model amplitude, and including optical magnification. FIG. 3 illustrates an example of an annular intensity profile 20 on a face of core 15 of fiber 16 . The normalized incident field amplitude or intensity of light is shown on the ordinate axis and the cross-sectional distance in microns from the center of the core 17 face of fiber 16 for each amplitude is shown by the abscissa axis. Two characteristics of optical element 16 , taken singly or in combination, may produce the light launch profile on fiber face core 15 and maintain robust compliance with the encircled flux conditions of the TIA specification. First, one surface 21 or 22 of optical element 13 may have a slope discontinuity at an optical axis 23 (r=0; r being the distance radially or perpendicularly from the optical axis, from the optical axis). This characteristic provides an axicon function to optical element 13 . The optical prescription for surface 22 , for example, may be a surface of revolution about optical axis 23 . This functionality may be implemented by including it in the surface prescription having an odd power of radius. An axicon function or lens may be used to convert a parallel laser beam into a ring, a doughnut shaped ablation or an annular intensity profile 20 shown in FIG. 3. A surface 22 discontinuity may put into effect the axicon function, phenomenon or lens to produce the annular intensity profile 20 on the face of fiber 16 . An illustration of surface 22 having a slope discontinuity at optical axis 23 is shown in FIG. 4 . Line 24 shows the slope of the upper part of surface 22 at optical axis 23 (r=0). Line 25 shows the slope of the lower part of surface 22 at optical axis 23 . As one follows surface 22 across axis 23 , there is a disruptive change of slope from slope 24 to slope 25 . Slope discontinuities may be implemented in various ways. FIG. 5 shows a slope or curvature discontinuity 34 as a small notch-like shape, cusp, indentation or protrusion in surface 22 at area 26 about optical axis 23 . Discontinuity 34 may be sharp, abrupt, rough or smooth. Discontinuity 34 may be of any shape or contour. Elsewhere, the slope may be continuous, such as a function of the distance from optical axis 23 or of the radius, except at optical axis 23 . Discontinuity 34 of slope of surface 23 may appear imperceptible to the eye. Apart from point or area 26 , surface 22 may aspherical or spherical. Surface 21 of optical element 13 may instead have the slope discontinuity. An illustrative example of lens surface specifications for optic element 13 may be in the following formulas, constants and variables for each of the surfaces. Surface 1 may be surface 21 and surface 2 may be surface 22 in FIG. 1 , or vice versa. Surface 1 z={cr 2 /[1+(1−(1 +k ) c 2 r 2 ) 1/2 ]}+A 1 r 1 +A 2 r 2 +A 4 r 4 +A 6 r 6 c=1/R; R=0.65943 mm k=−1.701593 A 1 =0 A 2 =0 A 4 =0.062933 A 6 =−0.01539 Surface 2 z={cr 2 /[1+(1−(1 +k ) c 2 r 2 ) 1/2 ]}+A 1 r 1 +A 2 r 2 +A 4 r 4 +A 6 r 6 c=1/R; R=−2.015644 mm k=−5.212050 A 1 =0.025409 A 2 =0.012167 A 4 =0 A 6 =0 The second characteristic which may be implemented to produce a launch profile having an annular intensity distribution or profile, similar to profile 20 of FIG. 3 , is the defocusing of optical element 13 relative to the face of core 15 at a fiber 16 end. This defocusing may result in an intensity profile sufficient to attain compliance with the TIA specification. Optical element 16 is defocused to a region corresponding to approximately ±8λ(f/) 2 . This characteristic may result in the annular or ring-like distribution of light intensity. The area of low or no intensity in the center of the ring or annular distribution may be referred to as the dark spot of Arago in a well-corrected optic. FIG. 6 reveals three focus positions of optical element 13 . Position 27 shows an annular intensity profile of light 14 launched on fiber 16 face of core 15 . The intensity is shown by coordinate I and the distance from optical axis 23 is shown by coordinate R. Position 28 shows a profile having the intensity of light 14 concentrated on optical axis 23 . Position 29 shows an annular intensity profile similar to the profile of position 27 . Position 28 is a focused place for the core 15 face and positions 27 and 29 are defocused places for the face of core 15 to receive launched light 14 . Either position 27 or 29 may be used to achieve the annular distribution of light intensity on the face of core 15 . FIG. 7 reveals an illustrative example of spot diagrams of the intensity profiles as seen on the core 15 end face of fiber 16 to show the defocus characteristic of system 10 for attaining the annular distribution of light intensity so as to comply with the TIA specification. Focus occurs at about 40 microns in FIG. 7 for spot 31 . The best annulus at defocus occurs at 0 microns of adjustment for spot 30 . Scale 32 shows the size of the intensity concentrations for the spots in the diagram. Optical system 10 may incorporate both the axicon feature and the annular PSF at defocus, even though either one alone may suffice for attaining compliance with the TIA specification. Incorporating the characteristics or elements is system 10 of FIG. 8 . It may be referred to as the “Ringlight” system. Light source 11 may be a VCSEL having about an 8 micron aperture. Between source 11 and optical element 13 is a BK7™ window 33 which may be part of the vacuum sealed package containing the VCSEL. The window is about 0.203 mm thick and its inner surface is about 1.145 mm from the base of the VCSEL. Window 33 is about 0.3 mm from surface 21 of optical element 13 . Optical element 13 is about 2.8 mm long and about 1.7 mm in diameter. Surface 21 may have an even asphere curvature and incorporate a slope discontinuity 26 on axis 23 . Surface 22 may have a SPS type or odd asphere surface. Lens surface 21 or 22 or both surfaces may include a hyperbolic (collimating) surface for receiving and collimating light originating from light source 11 . Also, optical element 13 may be shaped so that light reflected back-toward light source 11 is not focused at a location where light 12 is emitted by source 11 . Optical element 13 may be one piece and be made or molded from Ultem R 1010 which is a General Electric Company plastic. Surface 22 may be about 0.85 mm from the face of core 15 of multimode optical fiber 16 . VCSEL 11 may emit light signals 12 which propagate through window 33 , surface 21 and optical element 13 . The signals may exit element 13 as light 14 that may be launched into core 15 of fiber 16 . Although the invention has been described with respect to at least one illustrative embodiment, many variations and modifications will become apparent to those skilled in the art upon reading the present specification. It is therefore the intention that the appended claims be interpreted as broadly as possible in view of the prior art to include all such variations and modifications.","lang":"en","source":"USPTO_FULLTEXT","data_format":"ORIGINAL"}},"description_lang":["en"],"has_description":true,"has_docdb":true,"has_inpadoc":true,"has_full_text":true,"biblio_lang":"en"},"jurisdiction":"US","collections":[],"usersTags":[],"lensId":"080-568-236-964-783","publicationKey":"US_6961489_B2","displayKey":"US
