Fabrication of antiguide array lasers using a modulated-cap thin p-clad structure

Summary form only given. Because the required refractive-index variations can be achieved by precise etching of the cap layer in thin p-clad structures, we believe it may be possible to achieve in-phase operation of AlGaAs lasers routinely using the MCTC structure. In this work, the precise etching required to fabricate AlGaAs lasers was accomplished using a pulsed anodization/etching technique.
