The novel high-power vertical-cavity surface-emitting lasers(VCSEL) with radial bridge electrode is fabricated in order to improve the thermal characteristics and increase the out power of high power VCSEL.The analysis on the model of the high-power VCSEL shows the radial bridge electrode can reduce the electric and thermal resistance and the Joule heat of VCSEL.The radial brigde electrode and the conventional electrode high power VCSEL both with 200 μm aperture are made and tested comparatively.The testing results show that the differential resistance of the VCSEL is 0.43 Ω and the out power is 340 mW,1.7 times higher than the conventional device,which can operate at higher up to 80 ℃,and its thermal resistance is 0.95 ℃/mW.The temperature and opto-electric characteristics of radial bridge electrode high power VCSEL are much better than those of the conventional electrode high power VCSEL.
