Mach-Zehnder Interferometer Refractive Index Sensor Based on a Plasmonic Channel Waveguide
A Mach-Zehnder interferometer based on a plasmonic channel waveguide is proposed for refractive index sensing. The structure, with a small physical footprint of 20 × 120 μm(2), achieved a high figure of merit of 294. The cut-off frequency behaviour in the plasmonic channel waveguide resulted in a fl...
