Distributed feedback (DFB) lasers and distributed Bragg reflector (DBR) lasers using a grooved grating structure with 1.50 nm period are demonstrated on an InGaAs-GaAs strained quantum well active wafer without a re-growth process. The lasers exhibit a sharply controlled spectra with threshold currents of 14 mA as low as those of conventional Fabry Perot type lasers.
