Systems, methods and devices for holographic demultiplexing of optical signals
摘要：
Systems, methods and devices for holographic demultiplexing of optical signals that include constituent light signals of different wavelengths. A holographic demultiplexor includes a volume hologram having holograms for redirecting the constituent light signals. A dispersion element linearly disperses the optical signal, and the individual holograms of the volume hologram spatially reflect the constituent light signals back to the dispersion member at specific angles. The volume hologram spatially reflects the constituent light signals such that they are dispersed in two dimensions. The dispersion element then reflects the two dimensionally dispersed wavelengths to a two dimensional detector array.

用于包括不同波长的组成光信号的光信号的全息解复用的系统，方法和装置。 全息解复用器包括具有用于重定向组成光信号的全息图的体积全息图。 色散元件将光信号线性地分散，并且体积全息图的各个全息图在空间上以特定的角度将构成光信号反射回分散体。 体积全息图在空间上反映组成的光信号，使得它们分散在两个维度上。 然后，色散元件将二维分散的波长反射到二维检测器阵列。
