Enhanced all-optical switching by use of a nonlinear fiber ring resonator.

摘要: 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, phase of transmitted light varies rapidly with single-pass shift. combined action these effects leads to finesse-squared reduction threshold, allowing photonic that operate at milliwatt levels ordinary fibers.
