Abstract
Laser operation utilizing distributed feedback (DFB) in single heterojunction (SH) GaAs/GaAlAs diodes is reported. Laser wavelengths ranging from 8430 to 8560 Å were observed in various samples depending on grating period. The threshold current densities required were comparable to those of normal SH diodes.
