Fabrication and operation of first-orderGaInP/AlGaInP DFB lasers at roomtemperature

Abstract
The fabrication and operation properties of first-order distributed-feedback (DFB) GaInP/AlGaInP double quantum well lasers are reported. The lasers with DFB grating periods between 106 and 109 nm show stable single-mode operation in the visible range from 694.0 to 709.5 nm at room temperature.
