In-situ Time-domain Physical Adjoint Optimization of Complex Wave Dynamics
Hoyeong Kwon, Arunn Suntharalingam, Laureano Bulus-Rossini +1
Direct optimization of complex wave dynamics through the intrinsic evolution of physical systems is fundamentally limited by the lack of directly accessible gradients. Adjoint meth…
In-situ adjoint protocols for nonlinear PT-symmetric self-optimizing machines
Zheming Li, Lucas J. Fernández-Alcázar, Zin Lin +1
Adjoint methods provide a powerful route for gradient-based optimization, but their physical implementation is obstructed in generic nonlinear systems because the adjoint dynamics…
In-situ Adjoint Wave Control in Reconfigurable Non-Hermitian Nonlinear Systems
John Guillamon, William Tuxbury, Cheng-Zhen Wang +3
Complex multipath environments are usually avoided in wave-based information processing because repeated scattering creates many interfering propagation paths, obscuring controllab…
Optical Thermodynamics Beyond the Weak Nonlinearity Limit
Emily Kabat, Shrohan Mohapatra, P. G. Kevrekidis +1
Optical thermodynamics has recently emerged as a theoretical framework describing a Rayleigh-Jeans (RJ) modal power distribution of multimoded nonlinear photonic circuits. However,…
Observed enhanced emission at higher-order exceptional points in RF circuits
Nicolas Wyszkowski, Arunn Suntharalingam, Max Vitek +3
The Purcell effect -- stemming directly from the celebrated Fermi's Golden Rule -- links the enhanced emissivity of an emitter to the local density of states (LDoS) of a surroundin…
Synthetic Reflectionless Mode Exceptional Degeneracies via Emergent Local Symmetries
William Tuxbury, Lucas Fernandez-Alcazar, Tsampikos Kottos
We propose a new kind of physically realizable exceptional point degeneracies (EPDs) corresponding to synthetic reflectionless modes (SRM). These are solutions of an auxiliary wave…
