Method of adjusting the index of refraction of photonic crystals with laser micromachining to tune transmissions within the bandgap and structure

摘要

A photonic crystal comprising a waveguide made of material. The waveguide has a periodic set of holes. The material proximate to at least one of the holes in the periodic set of holes exhibits an index of refraction that has been modified by the application of laser energy relative to the material proximate to other holes in the periodic set of holes.
