Abstract:

The optical properties of single-mode rectangular fibers have been studied with the aim of improving past DH laserfiber coupling efficiency results. By local heating and careful fracturing, short, rectangular-to-round transition fibers can later be obtained for efficient overall laserround fiber coupling. The power loss due to rounding is known to be as low as 1 dB. A method of general applicability has been developed to measure core dimensions and numerical aperture of fibers. Coupling efficiency measurements were performed by a more reliable procedure for differentiating cladding from core output power than what has been generally used. Laserrectangular fiber efficiencies of 30 with a maximum of 50 have been obtained. If laser fluorescent power is accounted for to compare with other publications, the above figures become 46 and 71 respectively.
