N. Bouadma et al., 1.3-MU-M INGAP INASP MQW LASERS WITH LARGE SPOT-SIZE AND LOW-LOSS FIBER CHIP COUPLING FABRICATED BY A STANDARD BURIED HETEROSTRUCTURE PROCESS/, Electronics Letters, 32(17), 1996, pp. 1582-1583
1.3 mu m large spot-size laser diodes without a mode converter fabrica
ted by conventional buried heterostructure laser process, and using MQ
W core structure with low effective refractive index are demonstrated,
The devices show low coupling losses to cleaved fibre, good alignment
tolerances, and high temperature characteristics.
