Topological properties of reflection zeros of optical differentiators based on layered metal-dielectric-metal structures
Artem I. Kashapov, Evgeni A. Bezus, Dmitry A. Bykov +2
We investigate the topological properties of reflection zeros of three-layer structures consisting of a dielectric layer sandwiched between two metal layers, which can be used as o…
Design of cascaded diffractive optical elements generating different intensity distributions at several operating wavelengths
Georgy A. Motz, Daniil V. Soshnikov, Leonid L. Doskolovich +3
We consider the design of cascaded diffractive optical elements (DOEs) for generating specified intensity distributions for several incident beams with different wavelengths. For e…
Design of diffractive neural networks solving different classification problems at different wavelengths
Georgy A. Motz, Leonid L. Doskolovich, Daniil V. Soshnikov +4
We consider the problem of designing a diffractive neural network (DNN) consisting of a set of sequentially placed phase diffractive optical elements (DOEs) and intended for the op…
Designing robust diffractive neural networks with improved transverse shift tolerance
Daniil V. Soshnikov, Leonid L. Doskolovich, Georgy A. Motz +3
A wide range of practically important problems is nowadays efficiently solved using artificial neural networks. This gave momentum to intensive development of their optical impleme…
Vectorial spatial differentiation of optical beams with metal-dielectric multilayers enabled by spin Hall effect of light and resonant reflection zero
Leonid L. Doskolovich, Artem I. Kashapov, Evgeni A. Bezus +1
We theoretically describe and numerically investigate the operation of "vectorial" optical differentiation of a three-dimensional light beam, which consists in simultaneous computa…
