WebJul 15, 2024 · Optical nonreciprocal devices are of vast importance for signal processing and optical communication [1], [2], [3], and their realization needs the breaking of the Lorentz reciprocity theorem. The traditional way to realize optical nonreciprocity (ONR) is based on the magneto-optical Faraday effect. WebAbstract: Optical non-reciprocity, a phenomenon that allows unidirectional flow of optical field is pivoted on the time reversal symmetry breaking. The symmetry breaking happens in the cavity optomechanical system (COS) due to non uniform radiation pressure as a result of light-matter interaction, and is crucial in building non-reciprocal ...

WebMar 31, 2024 · Controlling higher-order quantum nonreciprocity by spinning an optical resonator. We study how to achieve, manipulate, and switch classical or quantum nonreciprocal effects of light with a spinning Kerr resonator. In particular, we show that even when there is no classical nonreciprocity (i.e., with the same mean number of photons for … WebThe results provide compelling evidence for strong and tunable inelastic scattering effects under the triple resonance condition, fulfilled for optical transitions between neighboring high-Q lattice modes of the appropriate symmetry, which originate from multipolar Mie resonances. A consistent interpretation of the underlying mechanisms is ... income tax brackets 2021 calculator
