在光泵浦下演示了由深蚀刻单量子阱线状有源区域组成的 1.55 /spl mu/m 波长 GaInAsP/InP 膜分布式反馈激光器的室温连续波操作。对于 10.7 /spl mu/m 宽和 40 /spl mu/m 长的装置，获得了 38 mW 的阈值功率。观察到薄膜波导结构固有的 65 nm 的大阻带宽度和 2.30 的低等效折射率。
Room-temperature, continuous-wave operation of a 1.55 /spl mu/m 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 /spl mu/m wide and 40 /spl mu/m 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.
