Band-pass filter and method for making photonic crystal for the band-pass filter










Image Number 12 for United States Patent #8149073.

A band-pass filter includes a photonic crystal having a local mode that generates a pass band in a stop band formed by Bragg reflection, a transmission channel that limits electromagnetic waves propagating in the photonic crystal to a mode in which an amplitude direction of an electrical field is a particular direction; and a magnetic field-applying unit for applying to the photonic crystal a DC magnetic field in a direction perpendicular to a propagation direction of the electromagnetic waves. The photonic crystal includes a periodic structure including a low permittivity dielectric member and a plurality of high permittivity dielectric members periodically arranged in the low permittivity dielectric member so that the Bragg reflection occurs in the periodic structure, and a magnetic member disposed in the periodic structure.
