Abstract
Room temperature continuous-wave operation of 2-/spl mu/m single-mode InGaSb-AlGaAsSb distributed-feedback (DFB) lasers has been realized. The laser structure has been grown by solid source molecular beam epitaxy (MBE). Single-mode DFB emission is obtained by first-order Cr-Bragg gratings on both sides of the laser ridge. For a cavity with 900 /spl mu/m length and 4 /spl mu/m width, the threshold currents are around 20 mA and the continuous-wave output power is 10 mW at a drive current of 200 mA at 20/spl deg/C. Monomode emission with sidemode suppression ratios of 31 dB has been obtained.
