Double‐heterostructure GaAs distributed‐feedback laser

The fabrication and operation of a GaAs–GaAlAs heterostructure distributed‐feedback laser are described in which fine optical corrugations (≈ 1150 A) are etched and regrown into the interface between two layers of the heterostructure. Laser operation has been observed before and after the growth of the final layer with optical pumping.
