4.1 Introduction

Photonic crystals are optical nanostructures with refractive indices that vary periodically, and are characterized by a photonic bandgap in terms of the energy of photons. Light with wavelengths that lie in the photonic bandgap cannot exist in the crystal, giving rise to completely different optical phenomena than in free space. These characteristics enable various interesting methods of optical ...
