Second-order supporting quadric method for designing freeform refracting surfaces generating prescribed irradiance distributions
Albert A. Mingazov, Dmitry A. Bykov, Evgeni A. Bezus +1
We consider the inverse problem of calculating a refracting surface that generates a prescribed irradiance distribution in the far field for a collimated incident beam. This proble…

Coherent perfect absorption and lasing in bimodal Fabry-Pérot interferometers
Dmitry A. Bykov, Evgeni A. Bezus, Leonid L. Doskolovich
Bimodal Fabry-Pérot interferometer is a model generalizing the conventional Fabry-Pérot interferometer, in which not one but two kinds of waves propagate between the interfaces.…

Optical computation of the divergence of a vector field using a metal-dielectric multilayer
Leonid L. Doskolovich, Artem I. Kashapov, Evgeni A. Bezus +1
We theoretically describe the optical computation of the divergence of a two-dimensional vector field, which is composed by the transverse electric field components of an incident…
