摘要: Chalcogenide glasses offer many attractive properties for all-optical signal processing including large Kerr nonlinearity (up to 500 × silica glass), an intrinsic ultrafast response time and low moderate two-photon absorption (TPA). These together with the convenience of a fibre format allow us achieve at peak power in very compact form. In this paper, several nonlinear functions will be demonstrated including: femto-second pedestal free, pulse compression; all-optic wavelength conversion; regenerator. addition, we show enhanced more efficient by tapering As2Se3 fibre. applications chalcogenide glass fibres are promising candidate materials processing.
