提出在一段掺铒光纤上制作一对光纤光栅可构成一种新型低功率高速光双稳器件。利用分布反馈耦合波理论结合掺铒光纤非线性特点分析了器件的运转和双稳阈值,表明在现有技术条件下,可实现纳秒微瓦级厘米尺寸器件的光双稳运转。
Abstract
It is proposed that a segmant of an Er doped fiber with a couple of fiber gratings on the ends may be used as a novel optical bistability device with low power and high speed. Operation and bistability threshold of the device are analysed in accordance with the distributed feedback couple mode theory and the nonlinear characteristic of the Er doped fiber. It is shown that a nanoseconds microwatts bistable operation of a centimeters sized device is realizable under nowaday technological conditions.
