摘要：
Controlling the propagation of electromagnetic radiation is described. A photonic bandgap medium is placed in the path of the electromagnetic radiation, the photonic bandgap medium comprising a photorefractive material. Control radiation is projected onto a surface of the photonic bandgap medium. The control radiation spatially varies a refractive index of the photorefractive material to control propagation of the electromagnetic radiation through the photonic bandgap medium.
