What is Photonic Crystal Waveguides Overview about?

This document summarizes key concepts from a lecture on photonic crystal waveguides: 1) Photonic crystals can confine light to a small volume by combining a 1D photonic crystal with index guiding in the other two dimensions. Introducing periodicity restricts the Brillouin zone. 2) A point defect in the periodic structure can create 3D confinement at specific bandgap frequencies. Photonic crystal slabs use a bandgap in the plane and index confinement out of plane to guide light in 3D. 3) Point defects i
