Subwavelength imaging using a solid-immersion diffractive optical processor
Demetri Psaltis, Carlo Gigli, Niyazi Ulas Dinç, Yang Li
Phase imaging is widely used in biomedical imaging, sensing, and material characterization, among other fields. However, direct imaging of phase objects with subwavelength resolution remains a challenge. Here, we demonstrate subwavelength imaging of phase ...
Springernature2024Predicting nonlinear optical scattering with physics-driven neural networks
Demetri Psaltis, Carlo Gigli, Ahmed Ayoub
Deep neural networks trained on physical losses are emerging as promising surrogates for nonlinear numerical solvers. These tools can predict solutions to Maxwell's equations and compute gradients of output fields with respect to the material and geometric ...
AIP Publishing2023Physics-informed neural networks for diffraction tomography
Demetri Psaltis, Carlo Gigli, Amirhossein Saba Shirvan, Ahmed Ayoub
We propose a physics-informed neural network (PINN) as the forward model for tomographic reconstructions of biological samples. We demonstrate that by training this network with the Helmholtz equation as a physical loss, we can predict the scattered field ...
SPIE-SOC PHOTO-OPTICAL INSTRUMENTATION ENGINEERS2022Xeno Nucleic Acid Nanosensors for Enhanced Stability Against Ion-Induced Perturbations
Ardemis Anoush Boghossian, Carlo Gigli, Alice Judith Gillen, Justyna Kupis-Rozmyslowicz
The omnipresence of salts in biofluids creates a pervasive challenge in designing sensors suitable for in vivo applications. Fluctuations in ion concentrations have been shown to affect the sensitivity and selectivity of optical sensors based on single-wal ...
