In this paper, a compact and broadband mode converter and demultiplexer based on multimode interference (MMI) is designed and experimentally demonstrated on silicon-on-insulator. We have designed a ...

Abstract: We propose a volume holographic demultiplexer in which each modal component can be separated spatially by phase matching characteristic of volume holograms combined with a phase conjugator.

Abstract: We designed a hexagonal arrayed OAM demultiplexer based on spiral transformation to match the output of a seven-core ring-core fiber, and fabricated the phase plates as diffractive optical ...
