▲ [20a-PB6-5] Wavelength-selective phase modulation using Fano-resonance-based metasurface
Keywords:Fano resonance, Metasurface, Phase modulation
The wavelength-selective phase modulation is demeonstrated using the Fano-resonance-based metasurface composed of asymmetric double rods with metal film as backplane. The phase modulation covers from 0 to 2 pi, which is possible only at the certain target wavelength with narrow bandwidth through Fano-resonance-based metasurface. The results based on the proposed metasurface have advantages of easy fabrication and it will be based on many applications such as filter, sensor, and switch in the NIR spectral region where there are many molecular vibration modes.
