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…
Inverse-Designed Meta-Optics with Spectral-Spatial Engineered Response to Mimic Color Perception
Chris Munley, Wenchao Ma, Johannes E. Fröch +7
Meta-optics have rapidly become a major research field within the optics and photonics community, strongly driven by the seemingly limitless opportunities made possible by controll…
Inverse Designed Extended Depth of Focus Meta-Optics for Broadband Imaging in the Visible
Elyas Bayati, Raphael Pestourie, Shane Colburn +3
We report an inverse-designed, high numerical aperture (~0.44), extended depth of focus (EDOF) meta-optic, which exhibit a lens-like point spread function (PSF). The EDOF meta-opti…
End-to-End Nanophotonic Inverse Design for Imaging and Polarimetry
Zin Lin, Charles Roques-Carmes, Raphaël Pestourie +3
By co-designing a meta-optical front end in conjunction with an image-processing back end, we demonstrate noise sensitivity and compactness substantially superior to either an opti…
Inverse designed metalenses with extended depth of focus
Elyas Bayati, Raphael Pestourie, Shane Colburn +3
Extended depth of focus (EDOF) lenses are important for various applications in computational imaging and microscopy. In addition to enabling novel functionalities, EDOF lenses can…
Topology optimization of freeform large-area metasurfaces
Zin Lin, Victor Liu, Raphaël Pestourie +1
We demonstrate optimization of optical metasurfaces over -- degrees of freedom in two and three dimensions, 100--1000+ wavelengths () in diameter, with 100+ paramete…
