Abstract

Buried heterostructure window lasers with micron wide waveguides suffer catastrophic damage at approximately 10 mW. When modified to incorporate nonabsorbing facets, the damage level can be increased by between one and two orders of magnitude. A lifetest of such "window" buried heterostructure lasers has been performed at 10, 20, 30 and 50 mW peak power and at 50°C and 70°C. The results project lifetimes of 180,000 hours at 20°C independent of power level, and show an activation energy of 0.48 eV. Undesirable fringes in the far field are caused by interference between the beam and waveguide sidewall scattered light. This problem is eliminated by adiabatically widening the waveguide near the output facet.
