The measurements of laser performances have been made in a continuous-wave mode at room temperature. The optical output power reached 20mW/facet. The interval quantum efficiency of the lasers was found to be 89% and the power efficiency amounted to 20%. The laser emitted in the fundamental spatial mode and operated on a single frequency over a wide range of currents and temperatures. The side longitudinal mode suppression was as great as 30dB. The emission wavelength could be continuously current-tuned within 0.7 to 1.2nm. The single longitudinal mode behavior was attributable to the photorefractive effect owing to DX centers in the Te-doped emitter layer acting as a saturable absorber. %8 2007-03-19
