  • 组播是波长路由光通信网络中的一项重要功能.提出并实验实现了基于高非线性光纤四波混频效应的全光组播方法,将一束载有数据的输入信号光和一束抽运光一起入射到一段高非线性光纤中,通过两个简并四波混频过程产生了两个携带该数据信息的闲频光,从而实现了单一信号的两信道组播,同时抽运光也会受到数据信息的调制.该方法的优点在于组播的实现只需要单一的抽运光源,而不需要再提供其他输入光,结构简单,组播光信号功率均匀、波长可调,并且具有进一步增加组播信道的能力.
    Multicasting is an important function of wavelength-routing optical communication networks. An all-optical multicasting is presented and experimentally demonstrated based on four-wave mixing (FWM) in highly nonlinear fibers. An input signal with data information together with a pump are injected into a highly nonlinear fiber and two idlers with new frequencies can be generated through two degenerate FWM processes, which carry the same data information as the input signal. The single input signal is copied to two channels and the pump can also be modulated by this data. The advantage of this scheme consists in the simple configuration, where only a single pump is needed and no other injected lights are required, the uniform powers and tunable wavelengths of the multicasting signals, and the capacity to further increase multicasting channel number.
