摘要
为了满足光学器件实现真正集成化的要求,提出一种基于光子禁带的全息光子晶体的多频道滤波器.在同一个记录介质上记录多个周期结构,可以在可见光频率范围内产生一系列光子禁带.通过改变制作波长,可以控制禁带的位置和宽度,从而实现多通道的光学滤波.
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.
