Far-off-resonant wave interaction in one-dimensional photonic crystals with quadratic nonlinearity
Johannes-Geert Hagmann, Lasha Tkeshelashvili, Kurt Busch +1
We extend a recently developed Hamiltonian formalism for nonlinear wave interaction processes in spatially periodic dielectric structures to the far-off-resonant regime, and invest…
