Demonstration of Nonlinear Effects in an Ultra Highly Nonlinear AsSe Suspended-core Chalcogenide Fiber
Résumé
Self-phase modulation and 10-GHz four-wave mixing are demonstrated in a low-loss and ultra-highly nonlinear suspended-core chalcogenide fiber. A record Kerr nonlinearity of 31 300 is measured and a direct evidence of fast response in time-resolved measurement of the nonlinear frequency conversion of high repetition rate is provided.
