FROZEN MODE IN PHOTONIC CRYSTAL WAVEGUIDE

Abstract

We propose a structure of 2D photonic crystal waveguide composed of hexagonal lattices of air holes in high index materials. Frozen mode regime can be observed within the photonic band gap. Light incident into the waveguide is coupled into two modes. One mode has enhanced amplitude and the other one has slow group velocity. Finite-different time-domain (FDTD) simulation is used to demonstrate the propagation of the slow mode.
