Low-loss-fibre coupling 1.3 mu m laser diodes with excellent temperatu
re characteristics were fabricated by employing thin (20nm) separate c
onfinement heterostructure layers. Fabricated LDs with an active layer
width of 1.5 mu m show singlemode-fibre coupling loss of 2.6dB, thres
hold current I-th of 16.4 (51.0) mA and high efficiency of 0.5 (0.3) W
/A at 25 (85)degrees C, respectively.
