利用差分群延迟（DGD）元件和偏振器实现了波分复用（WDM）光载无线电（Radio-over-Fiber）系统中多波长单边带（SSB）调制的同时产生。仿真结果表明，该滤波方案的滤波能力至少可用于8个信道。实验结果与模拟结果基本一致。实验还表明，系统的工作范围大于40 nm，覆盖了整个C波段。所有可能通道的边带抑制比均大于20 dB。
The simultaneous generation of multi-wavelength optical single sideband (SSB) modulation for wavelength division multiplex (WDM) Radio-over-Fiber systems using a differential group delay (DGD) element and a polarizer is constructed in the paper. Simulation proved the principle shows the capacity of such filtering scheme works for at least 8 channels. Experiment results accorded with simulations. Experiment also shows the operating range of the system is more than 40nm, which covers the whole C-band. The sideband suppression ratio for all possible channels is greater than 20dB.
