Abstract

The operation of antiguided array lasers is dependent on the creation of an effective refractive index step between the antiguide core and the interelement regions. The authors describe a novel technique, using zinc diffusion to disorder a superlattice, for creating the necessary index step in a 10 element antiguided laser array operating at 0.860 mu m. Output powers approach 400 mW per facet into a 3 degrees (FWHM) beam. Use of this fabrication technique removes the need for overgrowth.
