Abstract :
Fabrication and characteristics of epitaxial waveguide lasers with distributed Bragg reflectors are described. GaAs-(GaAl)As double-layered structures were grown by conventional liquid-phase-epitaxy (LPE) technique. Periodic corrugations were made by chemical etching through a photoresist grating mask. Laser action with clearly defined logitudinal modes was observed under optical pumping at liquid-nitrogen temperature.
