Paper Abstract

Some experimental aspects of the problem of efficient coupling between semiconductor waveguides and single-mode optical fibers are examined. Waveguides based on different InP/InGaAsP structures (single- and double-heterostructures, multi-quantum-well structures (MQW) with different degrees of dilution) have been fabricated, as well as modified single- mode fibers (i.e. with flat or lensed, straight or tapered ends). Coupling efficiency measurements between these structures have been performed, and the results are presented and discussed; the lowest coupling loss, about 0.5 dB, was obtained with a conveniently tapered fiber and a moderately diluted MQW structure (MD-MQW).
