Abstract :
A wavelength converter in the third window of fiber optic communication is designed. It is based on a periodically poled lithium niobate (PPLN) channel waveguide and cascaded second order nonlinearity effect. Both stationary and time domain investigations confirm that the device performance is improved by an integrated metal mirror, placed after an additional waveguide segment having suitable length. This is calculated in order to provide an optical path along which the co-propagating electromagnetic waves, changing their phase mismatch, can interact more efficiently after the mirror reflection
