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 ...
Full utilization of semi-Dirac cones in photonics
(American Physical Society, 2018-05-16)
In this study, realization and applications of anisotropic zero-refractive-index materials are proposed by exposing the unit cells of photonic crystals that exhibit Dirac-like cone dispersion to rotational symmetry reduction. ...
