基于线性腔光纤激光器产生可调微波信号的研究
Generation of Tunable Optical Microwave Signal Based on Linear Cavity Fiber Laser
摘要
Abstract
The tunable low-noise microwave signal has been widely applied in the fields of communication, radar,instrument measurement and so on. A scheme of tunable microwave signal generation was analyzed theoretically and demonstrated experimentally. Firstly,the stable triple-wavelength output was obtained using linear cavity Er-doped fiber laser with 980 nm high power semiconductor laser as a pump,based on energy transition of rare-earth element. Then the microwave signals of 10.521 GHz,21.249 GHz and 31.770 GHz were obtained respectively by beating triple-wavelength output based on optically heterodyne for generation of microwave signal,which had different polarization states respectively. Finally,the microwave tuning was realized among above three different frequencies by adjusting polarization controller and polarizer. This scheme has the advantages of simple structure,low cost,good output stability and high efficiency of frequency tuning.关键词
