Metasurface polarization splitter.
Polarization beam splitters, devices that separate the two orthogonal polarizations of light into different propagation directions, are among the most ubiquitous optical elements. However, traditionally polarization splitters rely on bulky optical materials, while emerging optoelectronic and photonic circuits require compact, chip-scale polarization splitters. Here, we show that a rectangular l...
متن کاملControlling the Polarization State of Light with Plasmonic Metal Oxide Metasurface.
Conventional plasmonic materials, namely noble metals, hamper the realization of practical plasmonic devices due to their intrinsic limitations, such as lack of capabilities to tune in real-time their optical properties, failure to assimilate with CMOS-standards, and severe degradation at elevated temperatures. Transparent conducting oxides (TCOs) is a promising alternative as plasmonic materia...

متن کاملPlasmonic Spectral Splitting in Ring/Rod Metasurface
We report spectral splitting behaviors based on Fano resonances in a novel simple planar metasurface composed of gold nanobars and nanorings. Multiple plasmonic modes and sharp Fano effects are achieved in a broadband transmittance spectrum by exploiting the rotational symmetry of the metasurface. The transmission properties are effectively modified and tuned by modulating the structural parame...
متن کاملAn Ultra-wideband and Polarization-independent Metasurface for RCS Reduction
In this paper, an ultra-wideband and polarization-independent metasurface for radar cross section (RCS) reduction is proposed. The unit cell of the metasurface operates in a linear cross-polarization scheme in a broad band. The phase and amplitude of cross-polarized reflection can be separately controlled by its geometry and rotation angle. Based on the diffuse reflection theory, a 3-bit coding...
