Artificial Second Order Non-Linearity in Photonic Crystals

Author(s):
A Feigel, Z. Kotler, and B. Sfez

We describe a technique for obtaining effective second order non-linearity X2 in non centro-symmetric Photonic Crystal made from centro-symmetric materials (e.g. glass, Ge or Si). The effect is based on the electric quadrupole transition, strong electromagnetic mode deformation and different contributions to the volume polarization from different parts of the photonic crystal1.
