无线光通信系统中佛克脱原子滤光器技术研究

Research on VADOF in Wireless Optical Communication System

首次将新型佛克脱原子滤光器 (VADOF)用于无线光通信 ,该系统既可用于地面光通信 ,也可用于卫星光通信系统。系统发射端采用光反馈、电扫描方案 ,将半导体激光频率锁定在 VADOF透射峰 ,接收端采用原子滤光器窄带滤光技术。实验表明 。

For the first time we apply new voigt anomalous dispersion optical filter (VADOF) in wireless optical communication.The system can be used both on ground and between satellites.With optical feedback and the control of MCU scanning procedure in the transmitter,the frequency of laser is locked within the VADOFs transmission peak.And narrow band with atomic optical filter is used in the receiver.Experiments prove the laser's frequency of transmitter fits the receiver's atomic filter very well.
