Optimal Gating for Dead-Time-Constrained Single-Photon Detectors

Frederic J. N. Jorgensen, Steven G. Johnson

We develop a Fisher-information framework for optimizing single-photon detector gating in periodic experiments, in contrast to previous more empirical or heuristic gating choices.…

Optimization of Active Reconfigurable Surfaces for Spatiotemporal MU-MIMO Wave Routing in Disordered Media: Application to the Cocktail-Party Problem

Frederic J. N. Jorgensen, Florent Dorlot, Constant Bourdeloux +4

We design an active reconfigurable intelligent surface (RIS) for acoustic multi-user multiple-input multiple-output (MU-MIMO) communication by solving a large-scale convex optimiza…

Fundamental Bounds and Efficient Estimation for Dead-Time-Constrained Event Detection, with Application to Single-Photon Lidar

Frederic J. N. Jorgensen, Steven G. Johnson

We develop an asymptotic statistical theory for parameter estimation from a class of non-i.i.d. periodic binary event-detection processes subject to nonparalyzable dead time and ga…

Inverse design for robust inference in integrated computational spectrometry

Wenchao Ma, Raphaël Pestourie, Zin Lin +1

We propose an inverse-design approach for computational spectrometers in which the scattering media are topology-optimized to achieve better performance in inference of unknown spe…

Time-reversal-symmetry bounds on electromagnetic fields

Wenchao Ma, Raphaël Pestourie, Steven G. Johnson

For linear electromagnetic systems possessing time-reversal symmetry, we present an approach to bound ratios of internal fields excited from different ports, using only the scatter…

Scalable freeform optimization of wide-aperture 3D metalenses by zoned discrete axisymmetry

Mengdi Sun, Ata Shakeri, Arvin Keshvari +5

We introduce a novel framework for design and optimization of 3D freeform metalenses that attains nearly linear scaling of computational cost with diameter, by breaking the lens in…

Towards optimal spatiotemporal wavefront shaping for the cocktail party problem with inverse design of an acoustic reconfigurable metasurface in disordered media

Raphael Pestourie, Constant Bourdeloux, Fabrice Lemoult +2

Multiple-user multiple-input multiple-output applications have recently gained a lot of attention. Here, we show an efficient optimization formulation for the design of all the tem…

Multifidelity deep neural operators for efficient learning of partial differential equations with application to fast inverse design of nanoscale heat transport

Lu Lu, Raphael Pestourie, Steven G. Johnson +1

Deep neural operators can learn operators mapping between infinite-dimensional function spaces via deep neural networks and have become an emerging paradigm of scientific machine l…
