1. 3-. mu. m InGaAsP distributed feedback laser
The fabrication and performance characteristics of 1.3-..mu..m InGaAsP distributed feedback (DFB) double-channel planar buried heterostructure (DCPBH) laser are reported. The lasers utilize a second-order grating with a periodicity of approx.3800 A for frequency selective feedback. The lasers have threshold currents in the range 25--35 mA at 30 /sup 0/C. The lasing mode shifts to longer wavelengths with increasing temperature at 1 A//sup 0/C. The dynamic linewidth under 40-mA current modulation is approx.1 A. The cw linewidth at an output power of 1 mW is approx.90 MHz. A monolithically integrated thermoelectric-controlled laser diode utilizing the DFB-DCPBH laser structure has been fabricated. The emission frequency of the laser can be continuously tuned by +- 4 A using 50-mA controller current.
