First-order optical spatial differentiator based on a guided-mode resonant grating
Dmitry A. Bykov, Leonid L. Doskolovich, Andrey A. Morozov +4
We present an experimental demonstration of a subwavelength diffraction grating performing first-order differentiation of the transverse profile of an incident optical beam with re…

Multifocal diffractive lens generating several fixed foci at different design wavelengths
Leonid L. Doskolovich, Evgeni A. Bezus, Andrey A. Morozov +3
We propose a method for designing multifocal diffractive lenses generating prescribed sets of foci with fixed positions at several different wavelengths. The method is based on min…
