System for efficient coupling to photonic crystal waveguides

摘要

In an optical coupling system, an optical coupler having a dielectric mirror or Gaussian beam mirror is used to efficiently couple optical signals to photonic crystal waveguides. Dielectric mirrors offer the advantage of optical coupling between dielectric waveguides and single mode photonic crystal waveguides. Various types of optical couplers may be implemented with or without a dielectric waveguide in the system.
