Optical microwave generation using two parallel DFB lasers integrated with Y-branch waveguide coupler被引量：2
《Chinese Physics B》2007年第5期1459-1463,共5页谢红云 王路 赵玲娟 朱洪亮 王圩 
Project supported by the National Natural Science Foundation of China （Grant No 90401025）. Acknowledgments The authors are grateful to the Multiple-function 0ptoelectronic Integration group, Institute of Semiconductors, CAS for sponsoring this project. We extend our thanks to Professor Wang Zi-Yu of Peking University for microwave signal testing.
A new device of two parallel distributed feedback （DFB） lasers integrated monolithically with Y-branch waveguide coupler was fabricated by means of quantum well intermixing. Optical microwave signal was generated in...
