Plasmonic Fano Nanoantennas for On-Chip Separation of Wavelength-Encoded Optical Signals

Guo, Rui; Decker, Manuel; Setzpfandt, Frank; Staude, Isabelle; Neshev, Dragomir; Kivshar, Yuri


Here we suggest and realize an ultracompact plasmonic spectral-band demultiplexer for telecommunication wavelengths integrated onto an optical waveguide that couples two wavelength-encoded optical signals in the O- and the C-band in opposite directions of a silicon waveguide. In this way, we demonstrate a plasmonic key element for on-chip optical data processing that can also be used as a functional link between on- and off-chip optical signals.
