For long distance optical interconnects,1.3-μm surface-emitting lasers are key devices.However,the low output power of several milliwatts limits their application.In this study,by introducing a two-dimensional photonic-crystal and using InAs quantum dots as active materials,a continuous-wave,13.3-mW output power,1.3-μm wavelength,room-temperature surface-emitting laser is achieved.In addition,such a device can be operated at high temperatures of up to 90 ℃.The enhanced output power results from the flat band structure of the photonic crystal and an extra feedback mechanism.Surface emission is realized by photonic crystal diffraction and thus the distributed Bragg reflector is eliminated.The proposed device provides a means to overcome the limitations of low-power 1.3-μm surface-emitting lasers and increase the number of applications thereof.
