Abstract
High-temperature operation of 1.3 μm AlGaInAs/InP strained multiple quantum well lasers is demonstrated. An excellent CW characteristic temperature of 111 K was obtained between 20 and 80°C and a record high operating temperature of 210°C was achieved with a 700 μm long laser under pulse excitation. Power reductions at a constant current with increasing temperature were also evaluated at 80°C to be -1.27 and -1.67 dB under pulse and CW excitations, respectively
