Abstract
I. 3μm large spot-size laser diodes (LDs) with a laterally tapered active layer have been fabricated with a conventional buried heterostructure laser process. Fabricated LDs with a cavity length as short as 225 μm show singlemode-fibre coupling losses of < 3dB, threshold currents of 4.7 and 18.0mA, and efficiencies of 0.54 and 0.37 W/A at 25 and 85°C, respectively.
