Abstract

Low-loss-fibre-coupling 1.3μm laser diodes with excellent temperature characteristics were fabricated by employing thin (20nm) separate confinement heterostructure layers. Fabricated LDs with an active layer width of 1.5μm show singlemode-fibre coupling loss of 2.6dB, threshold current Ith of 16.4 (51.0)mA and high efficiency of 0.5 (0.3) W/A at 25 (85)°C, respectively.
