— Background: Chaos is considered hypersensitive to conditions of a system and is often thought to be unpredictable and difficult to explain. However, recent work has shown that chaos can be added as noise to improve amplification of weak signals through stochastic resonance. Stochastic resonance has …

— A non-reciprocal transmission device based on PT symmetry was previously theorized but never before constructed and shown to work at useful optical wavelengths. The new structure allows creation of the miniaturized optical isolation function without use of the century+ known Faraday effect. Optica…
