Abstract

We report a 1.8 μm two-section distributed Bragg reflector laser using butt-jointed InGaAsP bulk material as the waveguide core layer. The threshold current is 17 mA and the output power is 8 mW on average. The threshold current, output power, and emitting wavelength dependences on temperature are measured. The obtained wavelength tuning range is 10 nm. This device has potential applications in simultaneous multiple-gas detection.
