Abstract
We report on all-optical switching of a 900-nm signal in a two-mode si lica fiber based upon a resonant nonlinearity introduced by phosphorus color centers in a 22-cm irradiated P2O3-SiO2 fiber. Full switching w as observed with only 1 mu J of absorbed 532-nm pump energy, with a pr ojected response time under 10 ns. This switch required a peak power t wo orders of magnitude lower than for a fiber Kerr effect device opera ted under identical conditions.
