We demonstrate experimentally the stable continuous-wave (CW) single-mode operation of Bragg reflection waveguide (BRW) lasers from 10 to 100°C. The threshold characteristics, quantum efficiency, gain, and self-heating characteristics are investigated in detail. Threefold enhancement in the optical confinement is achieved using these BRW structures for a core width two times that of their edge-emitting total internal reflection counterparts. The device shows also the high gain and characteristic temperature (~197 K) under CW operation from 10 to 100°C. The mode stability is analyzed by the calculated mode reflection spectrum, injection-current-dependent lasing spectrum, and near-field patterns.
