Photonic Crystal Resonator Biased with Externally Applied Voltage

摘要

in accordance with the present invention a photonic crystal (photonic crystal) inside the cavity resonator cavity of air (vacuum) co (cavity) is the resonator. The photonic crystal is created by arranging the dielectric bars in a periodic two-dimensional photonic crystal. A periodic array of dielectric rods can be formed in various ways, the optical band gap of the photonic crystal (photonic band gap) is configured to facilitate forming the desired frequency band. Making removal of the defect (defect) at least one bar in the two-dimensional photonic crystal composed of the dielectric rod. The point (local) and the resonator of the cavity type defects is combined with the external electromagnetic radiation source. Ray (line) is added to a combination of defective external electromagnetic wave source and the resonator. The line defect waveguides becomes a role because the bars are removed to create a form of electromagnetic lines it can be moved along this fault line. Line defect is combined with an external electromagnetic resonators source. Each end of the dielectric rod is covered with a metal sheet of the top and bottom. Placed above and below the isolated region on the metal sheet at least one of the two metal plates is separated into two or more isolated metal plate. Isolating region is to intersect the line defect. The width of the isolation region is small enough to make than the wavelength of the electromagnetic waves will progress smoothly through the line defect. The combination of the resonator to the external electromagnetic radiation source is an AC voltage having a frequency of an electromagnetic wave is formed between the two metal plates blocking the cavity resonator. Applying a DC voltage, pulse voltage or the like to the metal sheet, such as is obtained by adding a variation of the AC voltage. When applying a DC voltage is obtained by the DC voltage to AC voltage biased.
