Broadband and polarization-independent asymmetric transmission of visible light through a three-dimensional trapezoidal metallic metasurface
(OSA - The Optical Society, 2018-09-01)
In modern optical applications, it has become an important need to flow light unidirectionally. An optical diode realizes this task as an electrical counterpart manipulates the flow of electrons in semiconductor materials. ...
Highly controlled Bloch wave propagation in surfaces with broken symmetry
(OSA - The Optical Society, 2018-06-01)
We propose and demonstrate reduced symmetry photonic surfaces providing highly controlled Bloch wave propagation. The backward and dual directional propagations have been observed in the proposed low-symmetric periodic ...
Enhanced superprism effect in symmetry reduced photonic crystals
(American Institute of Physics Inc., 2018-09-24)
We propose compact S-vector superprism providing broadband wavelength sensitivity within a/λ = 0.610-0.635, where "a" is the lattice constant, λ is the incident wavelength, and S denotes the Poynting vector. The reported ...
Polarization-insensitive beam splitters using all-dielectric phase gradient metasurfaces at visible wavelengths
(OSA - The Optical Society, 2018-09-15)
Beam splitters play important roles in several optical applications, such as interferometers, spectroscopy, and optical communications. In this study, we propose and numerically examine polarization-insensitive beam splitters ...
