摘要：
A demonstration of a high-power, high-speed 980 nm vertical-cavity surface-emitting laser array with continuous-wave power of greater than 120 mW and frequency response over 7.5 GHz at room temperature is reported. Experimental results show that copper plating the array elements and flip-chip bonding provides effective thermal management as well as offering uniform current distribution at microwave frequencies. This is verified by the radial dependence of modulation bandwidth. These arrays may be useful for short-range light detection and ranging or free-space optical communications systems.
