All-optical wavelength conversion based on PPLN waveguide
In this paper we demonstrated a novel all optical wavelength conversion(AOWC) technique which employs the cascaded second order nonlinearity in passive optical waveguides. Using a 50 mm periodically poled LiNbO\-3 waveguide
we realized over 70 nm conversion bandwidth at 1.55 μm band and demonstrated the ability of multiply wavelength channels simultaneous conversion.
