Notes: The fabrication and performance characteristics of 1.3-μm InGaAsP distributed feedback (DFB) double-channel planar buried heterostructure (DCPBH) laser are reported. The lasers utilize a second-order grating with a periodicity of ∼3800 A(ring) for frequency selective feedback. The lasers have threshold currents in the range 25–35 mA at 30 °C. The lasing mode shifts to longer wavelengths with increasing temperature at 1 A(ring)/°C. The dynamic linewidth under 40-mA current modulation is ∼1 A(ring). The cw linewidth at an output power of 1 mW is ∼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(ring) using 50-mA controller current.
