Non-reciprocal photonic gauge potential and non-equilibrium thermal metaphotonics for the control of light and heat
Abstract
Our program is centered around two thrusts. In Thrust 1, we will develop theconcept of photonic gauge potential, which arises from"" photonic structures undergoing refractiveindex modulation, as the mechanism to achieve non-reciprocal light flow in real space, an"d in asynthetic space with a frequency dimension in order to manipulate the spectrum of light. We willalso develop large-scale num"erical techniques that enable first-principle simulations andoptimizations of dynamic meta-photonic structures. In Thrust 2, we wil"l explore thermodynamicsof meta-photonic structures. We will build upon our recent demonstrations of day-time radiativecooling and" develop photonic structures with ultra-broad-band spectral control spanning both solarand thermal wavelength ranges. Also, while m"ost design of thermo-photonic structures arefundamentally constraint either by local thermal equilibrium conditions or by reciproci"ty, wepropose to explore structures that are not subject to these constraints in order to create newcapabilities for thermal radia"tion control.
