摘要
提出了一种采用光纤光栅滤波器获得具有一定间隔双波长成分的光脉冲光谱实现毫米波副载波光信号产生的方法。利用逆工程算法,设计了一种变迹叠栅(Moiré)光纤光栅滤波器,给出了相应的模拟结果;并在实验上初步制作了相应的光纤光栅滤波器,验证其可行性。同时基于所设计的光纤光栅和波分复用技术,提出了一种频移键控光纤无线通信系统Radio Over Fiber系统,为下一代的高速大容量的光纤无线通信系统系统提供一种可行的备选解决方案。
A method is proposed to realize millimeter-wave subcarrier optical signal generation by using a doublewavelength optical spectrum of a certain distance with fiber grating filter. The feasibility is analyzed by designing an apodized moir6 fiber grating in which Fourier transformation reverse-engineering method is used, the simulation result is also presented, and the related fiber grating filter is fabricated experimentally. Moreover, based on the designed fiber grating and the technology of wavelength division multiplexing, a frequency shift keying radio-overfiber communication system is suggested, and the proposed scheme may be taken as one of the candidates for the next generation high-speed and large-capability radio-over-fiber system.
