Abstract
The authors have fabricated low-threshold 670nm GaInP/AlGaInP ridge wa veguide lasers based on a combined dry-and wet-etching technique. Mini mum CW threshold currents of 10.4mA with a differential quantum effici ency of 72% have been obtained for a 2 mu m wide and 200 mu m long tri ple quantum well laser. A maximum output power of 23mW per facet is ac hieved for this uncoated device. Single transverse mode operation is o bserved for output powers of up to 14mW per facet.
