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…

Efficient inverse design of large-area metasurfaces for incoherent light
Raphaël Pestourie, Wenjie Yao, Boubacar Kanté +1
Incoherent light is ubiquitous, yet designing optical devices that can handle its random nature is very challenging, since directly averaging over many incoherent incident beams ca…
