Photonic crystal system and method of controlling/detecting direction of radiation propagation using photonic crystal system

摘要

A photonic crystal system and a method for controlling the direction of radiation propagation are disclosed. The photonic crystal system includes a photonic crystal and a deformation source positioned to deform the photonic crystal. The photonic crystal system optionally includes a radiation source that emits radiation at a frequency within a frequency range over which the photonic crystal exhibits a negative index of refraction.
