Time-varying media, dispersion, and the principle of causality
TT Koutserimpas, F Monticone - Optical Materials Express, 2024 - opg.optica.org
The article reviews general properties of time-varying dispersive materials. We first briefly
discuss different dispersion models that have been proposed in the literature, the role of the …

Wavelength-independent Bragg-like reflection in uniaxial bi-anisotropic media
SF Koufidis, MW McCall - JOSA B, 2023 - opg.optica.org
We have recently shown that a uniform birefringent medium exhibits a circular Bragg
phenomenon that relies solely on resonant tuning of the medium's parameters, rather than …

Dynamic polarization control by adjustable cross-polarization coupling in time-periodic anisotropic media
M Alavi, AN Askarpour - JOSA B, 2024 - opg.optica.org
We study wave propagation in an anisotropic medium whose optic axes vary periodically in
time. This variation, in addition to generating frequency products, lifts the degeneracy …
