Abstract :
High-performance distributed feedback (DFB) double-channel planar buried-heterostructure (DCPBH) lasers (λ=1.3 μm) with a modulation bandwidth as high as 5GHz are reported. The frequency response of these InGaAsP/InP lasers is improved by formation of a double-channel (DC) DCPBH structure with a 20 μm-wide mesa. Threshold currents range between 17 mA and 35mA. Sigle-mode operation is observed over a temperature range of 100 K with a sidemode suppression of better than 36 dB at 25°C.
