摘　　要：A compact and stable three-port optical gate has been successfully fabricated by monolithically integrating a simple photodiode and an electroabsorption modulator. The gate shows an excellent DC logic ＂and＂ function with different load resistors. Its dynamical characteristics without packaging have also been measured. We observed a dynamic extinction ratio of over 7dB with a 95012 load resistor and a 7mW control light power at 622Mbit/s.通过在InP基上单片集成光探测器和调制器,制作了三端光逻辑门.在不同的负载电阻下,器件显示了良好的"与"门功能.对芯片进行了622MHz的动态测试;在950Ω负载条件下,只需要约7mW的控制光功率即可获得大于7dB的动态消光比.
