Diffractive neural networks for mode-sorting with flexible detection regions
Kaden Bearne, Alexander Duplinskiy, Matthew J. Filipovich +1
Mode-sorting is a procedure that decomposes a light field into a basis of transverse modes, directing each mode into a separate spatial location, allowing the constituent mode inte…

Tsang's resolution enhancement method for imaging with focused illumination
Alexander Duplinskiy, Jernej Frank, Kaden Bearne +1
A widely tested approach to overcoming the diffraction limit in microscopy without disturbing the sample relies on substituting widefield sample illumination with a structured ligh…

Passive superresolution imaging of incoherent objects
Jernej Frank, Alexander Duplinskiy, Kaden Bearne +1
We investigate Hermite Gaussian Imaging (HGI) -- a novel passive super-resolution technique -- for complex 2D incoherent objects in the sub-Rayleigh regime. The method consists of…
