Spatial-Mode Demultiplexer Using 1550-Nm-Band Angularly Multiplexed Volume Holograms

A volume-holographic spatial-mode demultiplexer for the 1550-nm band is created and described, for the first time. Angularly multiplexed volume holograms combined with a dual-wavelength method achieve three-mode demultiplexing with a crosstalk of less than −20 dB.
