High power operation at high temperature of AlGaInAs/InP widely tunable BH laser


We fabricated high performance 1550 nm widely tunable lasers which are integrated 12-channel DFB laser array and SOA with buried-heterostructure configuration based on the AlGaInAs/InP system. We investigated the lasing performance at high temperature of the widely tunable laser. The output power as high as 90 mW at a temperature of 70 °C was achieved… (More)
