We predict dramatically reduced switching thresholds for nonlinear optical devices incorporating fiber ring resonators. The circulating power in such a resonator is much larger than the incident power; also, the phase of the transmitted light varies rapidly with the single-pass phase shift. The combined action of these effects leads to a finesse-squared reduction in the switching threshold, allowing for photonic switching devices that operate at milliwatt power levels in ordinary optical fibers.
我们预测,对于包含光纤环形谐振器的非线性光学器件,其开关阈值将大幅降低。这种谐振器中的循环功率远大于入射功率;此外,透射光的相位随单程相移快速变化。这些效应的综合作用导致开关阈值降低至精细度平方,从而实现了能在普通光纤中以毫瓦功率水平运行的光子开关器件。
