Outline of Final Research Achievements

This research proposed and evaluated a novel optical mode multiplexer / demultiplexer based on angled-multimode interference (a-MMI) waveguide for realizing compact size, low loss, high integrated mode multiplexer / demultiplexer . As a result, the optical mode demultiplexer based on a-MMI waveguide shows the possibility of demultiplexing fundamental and first order mode, however, the mode-crosstalk between fundamental and first order mode is not sufficient, that is due to the insufficient focal point shift between fundamental and first order mode, for transmission system. On the other hand, another type of mode multiplexer / demultiplexer based on Rowland circular type has been investigated, and the principle has also been confirmed for the mode multiplexer / demultiplexer.
