All-optical switching and two-photon absorption effects in long- period gratings in As2Se3 chalcogenide fibre
- We show that two-photon absorption can actually improve the performance of a long-period grating switch in highly nonlinear As2Se3 chalcogenide fibre. We demonstrate numerically and experimentally low power switching behavior at pulse intensities around 65MW/cm2.
