Paper Abstract

A design for a compact Si photonic two mode demultiplexer for mode division multiplexing (MDM) applications is presented. The design uses the self-imaging in multimode interference structures to achieve MDM with an insertion loss less than 0.5 dB and a cross talk better than 20 dB over the C band. The imaging is achieved within a length that is half the length reported in the literature, and its overall dimensions are 42 μm×3 μm. The minimum cross talk is affected by the structure geometry. The tolerance of the design to variations in the dimensions is also studied.
