Ultra-compact plasmonic wave splitter in NIR domain

In this study we describe the design, the simulation and the characterization of a NIR domain plasmonic wavelength demultiplexer integrated on SOI waveguide. The reported device is made of a few chains of gold nano cut wires with a total feature dimensions of 4μm×4μm and is acting as a 1.3/1.5 μm wavelength demultiplexer for optical communication. This is the smallest footprint size wavelength demultiplexer in this frequency band to our best knowledge at this date. The modeling and experimental results show that the considered approach opens the avenue toward a new generation of ultra-compact optical devices.
