Abstract :
We report on the visible (660 nm) monolithic resonant-cavity light-emitting diode grown by solid source molecular beam epitaxy. The device consisted of a 1 Å-thick AlGaInP-based optical active region surrounded by AlGaAs-based distributed Bragg reflectors. Current aperture for the emitter was formed by lateral selective wet thermal oxidation. High continuous-wave output power of almost 2 mW with 5-nm linewidth and peak wall-plug efficiency of 3% were attained without heatsinking from the 80-μm device. This device was very resistant against temperature variations
