Non-reciprocal optical components such as isolators and circulators are crucial for preventing catastrophic back -reflection and controlling optical cross talk in photonic systems. While non-reciprocal devices based on Brillouin intermodal transitions have ...
Terahertz and far-infrared techniques are combined with complementary Raman and inelastic neutron scattering results to probe the low-energy phonon dynamics of archetypal antiferroelectric candidate - francisite (Cu3Bi(SeO3)(2)O2Cl). The combined results c ...
The integration of transition-metal dichalcogenides (TMDs) with non-planar substrates such as nanopillars provides a way to spatially modify the optical properties mainly through the localized strain. Similar studies to date have utilized insulating SiO2 n ...
