Paper Abstract

Using the coupled mode approach we present theoretical modelling of quasi phase-matched parametric amplification in a planar waveguide in which, the pump and signal are guided while the idler is radiated into the substrate. Numerical results on optimum waveguide parameters (which provide maximum signal gain) for a given pump and signal wavelengths are presented for a periodically domain reversed, proton-exchanged LiNbO3 planar waveguide. The proposed configuration is shown to provide large signal gain bandwidth.
