Polarization Multiplexed Optical Bullseye Antennas



We present and analyze a novel optical antenna structure in the form of a polarization multiplexed bullseye antenna with a central nanoaperture. By adjusting the parameters of two, orthogonally oriented, partial bullseye structures, the resonance response for each polarization can be tailored to a specific wavelength. Constructing these dual-polarization structures in aluminum, we predict intra-aperture intensity enhancements exceeding 20 at two independent resonance wavelengths spanning the UV–visible spectrum. Moreover, these resonances share significant intra-aperture excitation volumes.
