A numerical study of the all-optical switching properties of solitons in an erbium-doped nonlinear fiber coupler is presented. The small gain provided by the erbium both lowers and sharpens the switching threshold, while producing pulse-compression factors of 3 to 9. As a result, we show that it is possible to achieve all-optical switching, amplification, and compression of short pulses in a single device.
本文给出了掺铒非线性光纤耦合器中孤子全光开关特性的数值研究。掺铒所提供的小增益既降低了开关阈值又使其变尖锐，同时产生了3到9的脉冲压缩因子。结果表明，在单个器件中实现短脉冲的全光开关、放大和压缩是可能的。
