We report the theoretical and experimental investigation of switching in a nonlinear twin-core erbium-doped fiber coupler. It is shown that switching action takes place at a power of a fraction of 1 mW. Thus it provides a practical means of fabricating an all-optical fiber switch.
我们报道了对非线性双芯掺铒光纤耦合器中开关现象的理论和实验研究。结果表明，开关动作在功率为几分之一毫瓦时发生。因此，它为制造全光纤光开关提供了一种切实可行的方法。
