Abstract
The facets of GaAs-AlGaAs ridge waveguide (RW) laser diodes were passi vated using (NH4)(2)S-x. The effectiveness of this procedure was check ed by electroluminescence power-voltage-current (P-V-I) measurements t hat provide information on the changes in the density of surface state s, Using this nondestructive method, the degradation of the passivatio n under ambient atmosphere has been studied. Capping with silicon nitr ide is found to stabilize the sulfur passivation and avoid degradation .
