标题(英语)

OPTICAL CDMA ENCODER USING CHIRPED PHOTONIC CRYSTALS


摘要(英语)

An optical CDMA encoder using chirped photonic crystals is provided to implement encoding for a frequency domain and a time domain at the same time by generating sequential time delay according to a wavelength by using the two dimensional plat chirped photonic crystals, manufacture an encoder of a ten or more micro unit through a signal board, perform active pulse control through minute change induction of a refractive index, and increase non-linear effects through localization of an optical signal. A first photonic crystal waveguide(20) forms a longitudinal line defect in a two dimensional plate chirped photonic crystal(10) where a size of a photonic crystal hole or column, or a refractive index is sequentially varied, and applies an optical signal. An input unit(30) applies an optical signal to the first photonic crystal waveguide. A second photonic crystal waveguide(40) is spaced from the first photonic crystal waveguide as much as a predetermined interval, and forms a longitudinal line defect in the two dimensional plate chirped photonic crystal. The optical signal inputted into the first photonic crystal waveguide is localized and coupled according to wavelengths. An output unit(50) outputs the optical signal from the second photonic crystal waveguide.
