Abstract :
Enhanced nonlinear parametric conversion is demonstrated via doubly resonant coupling to leaky eigenmodes in photonic crystal waveguides. In particular, we show an example of sum-frequency generation. This technique can be extended into a useful spectroscopic tool to access more wavelengths and wavevectors by considering difference-frequency generation and non-collinear geometries.
