Abstract

Room-temperature, continuous-wave operation of a 1.55 μm wavelength GaInAsP/InP membrane distributed feedback laser consisting of deeply etched single-quantum-well wire-like active regions is demonstrated under optical pumping. A threshold power of 38 mW was obtained for a 10.7 μm wide and 40 μm long device. A large stop-band width of 65 nm and a low equivalent refractive index of 2.30, which are inherent in a thin membrane waveguide structure, were observed
