摘要:
We demonstrate room-temperature pulsed current-injected operation of InGaAlN heterostructure laser diodes with mirrors fabricated by chemically assisted ion beam etching, The multiple-quantum-well devices were grown by organometallic vapor phase epitaxy on c-face sapphire substrates. The emission wavelengths of the gain-guided laser diodes were in the range from 419 to 432 nm, The lowest threshold current density obtained was 20 kA/cm(2) with maximum output powers of 50 mW, Longitudinal Fabry-Perot modes are clearly resolved in the high-resolution optical spectrum of the lasers, with a spacing consistent with the cavity length, Cavity length studies on a set of samples indicate that the distributed losses in the structure are on the order of 30-40 cm(-1).
