PHOTONIC CRYSTAL WAVELENGTH DEMULTIPLEXER

摘要

A micro type photonic crystal wavelength splitter using an inversed image of wavelength is provided to easily separate many wavelengths by inserting a photonic crystal. A micro type photonic crystal wavelength splitter using an inversed image of wavelength comprises the followings: an input unit(10) of a single-mode waveguide receiving a wavelength mixed in a photonic crystal; a reflection crystal unit(20) which is inserted in order to reflect a specific wave in a multiple mode waveguide separating the mixed wavelength; a reflection output unit(30) of the single-mode waveguide outputting a wavelength reflected from the reflection decision unit; and a passage output unit(40) of a single waveguide outputting the wavelength which is not reflected in the reflection decision unit.
