英文摘要	A fiberoptic coupling system comprising a phased array semiconductor laser and a squashed multimode light transmitting fiber. The squashed input end has an oblong, preferably elliptical, or polygonal cross-section with major and minor core widths. The major width decreases toward an output end which preferably has a circular cross-section. The minor width may increase toward the output end or remain constant. This increase and decrease correspond to the characteristic laser light beam widths and divergences in planes parallel and perpendicular to an active region of the laser such that the fiber core widths are at least as large as the laser light beam widths and the fiber has input numerical apertures that cause the beam to be coupled at the divergences. This system has a light coupling efficiency of at least 70 percent.
