摘      要：We demonstrate a technique of temperature compensation for 1.3μm InAs/GaAs quantum-dot(QD)lasers by facet coating *** key point of the technique is to make sure that the mirror loss of the lasers decreases as the temperature *** realize this, we design a type of facet coating by shifting the central wavelength of the facet coating from 1310nm to 1480nm, whose reflectivity increases as the emission wavelength of the lasers ***, the laser with the new facet coating exhibits a characteristic temperature doubled in size and a more stable slope efficiency in the temperature range from 10℃ to 70℃, compared with the traditional one with a temperature-independent mirror loss.
