Title: Waveguide, multiplexer, and interface structures for mode division multiplexing on silicon

As an independent multiplexing dimension, mode division multiplexing has drawn interests on optical interconnect based on silicon. It can help increasing the communication capacity by folders requiring no strict wavelength control as in conventional wavelength division multiplexing system. In this presentation, we will present our recent works on the bus waveguide, mode multiplexer, and fiber interface structures for mode division multiplexing on silicon. Densely packed waveguide array structure is introduced for the bus waveguide, which shows a spatially distinguished mode profiles and benefits for a convenient multiplexing structure using simple linear tapers and butt coupling. Propagation and bending losses are studied. Multi-mode crossing and coupler are introduced. Grating coupler for a perfectly vertical fiber is also realized, which can be used for interfacing of the silicon mode division multiplexing chip with multi-core fibers.

Link for the video of the presentation can be provided internally.
