Abstract
A multi-wavelength bandstop filter is proposed and numerically demonstrated using the sum-frequency generation (SFG) effect in a periodically poled lithium niobate (PPLN) waveguide. The proposed device achieves channels number reconfigurable, central wavelength of each channel independently tunable and extinction ratios (ERs) equalized via all-optical methods.
Keywords: All-optical, tunable and reconfigurable filter, multi-channel, periodically poled lithium niobate, nonlinear optics
