Abstract
To achieve highly integrated elements,the holographic fabrication of multi-channel filter based on photonic band-gaps is approached.A series of band-gaps in visible region can be obtained by recording a multi-periodic structure in a volum hologram.The position and width of the band-pass can be controlled by the wavelength of recording beam,so a multi-channel filtering is easily realized.
