Abstract
We report on the high-temperature performance of high-power GaInNAs broad area laser diodes with different waveguide designs emitting in the 1220-1240-nm wavelength range. Large optical cavity laser structures enable a maximum continuous-wave output power of >8.9 W at T = 20 degrees C with emission at 1220 nm and are characterized by low internal losses of 0.5 cm(-1) compared to 2.9 cm(-1) for the conventional waveguide structures. High-power operation up to temperatures of 120 degrees C is observed with output powers of >4 W at T = 90 degrees C. This laser diode showed characteristic temperatures of T(o) = 112 K and T(1) = 378 K.
