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…
