Strongly enhanced backward second-harmonic generation with slow light in a two-dimensional photonic crystal

Iliew, Rumen; Etrich, Christoph; Pertsch, Thomas; Lederer, Falk; Kivshar, Yuri


We obtain greatly enhanced conversion efficiencies of backward second-harmonic generation by exploiting small group velocities at phase match in a two-dimensional quadratically nonlinear photonic crystal. The efficiencies obtained from a modal approach are rigorously confirmed.
