Adjoint-optimized metasurfaces for compact mode-division multiplexing. [PDF]

ACS Photonics, 2022
Optical fiber communications rely on multiplexing techniques that encode information onto various degrees of freedom of light to increase the transmission capacity of a fiber. However, the rising demand for larger data capacity is driving the need for a multiplexer for the spatial dimension of light.

Silicon Chip-to-Chip Mode-Division Multiplexing [PDF]

Optical Fiber Communication Conference, 2018
A chip-to-chip mode-division multiplexing connection is demonstrated using a pair of multiplexers/demultiplexers fabricated on the silicon-on-insulator platform. Successful mode multiplexing and demultiplexing is experimentally demonstrated, using the LP01, LP11a and LP11b modes.
