Abstract

We present detailed experimental and numerical analyses of nonlinear all-optical switching in long-period gratings (LPGs) in As 2 Se 3 chalcogenide fiber. We characterize the nonlinear propagation of picosecond pulses through the LPG and observe nonlinear switching at optical peak powers around 55 W . This is 2 orders of magnitude lower than previously demonstrated in silica fibers, owing to the very strong Kerr nonlinearity in As 2 Se 3 chalcogenide glass. The results are discussed in the context of applications in passively mode-locked lasers and all-optical regenerators.
