Extraordinary magneto-optical effects and transmission through metal-dielectric plasmonic systems.
TLDR
Calculations demonstrate that in such structures the Faraday effect spectrum has several resonance peaks in the near-infrared range, some of them coinciding with transmittance peaks, providing simultaneous large Faraday rotation enhanced by an order of magnitude and highTransmittance of about 35%.
Numerical Methods for Calculating Poles of the Scattering Matrix With Applications in Grating Theory
Waveguide and resonant properties of diffractive structures are often explained through the complex poles of their scattering matrices. Numerical methods for calculating poles of the scattering…
Design of TIR optics generating the prescribed irradiance distribution in the circle region.
TLDR
It is shown that point source approximation is acceptable in cases when the size of the light source is 5 (or more) times less than the distance to the inner surface of the optical element.
Optical computation of the Laplace operator using phase-shifted Bragg grating.
TLDR
It is shown that the PSBG enables optical computation of the spatial Laplace operator of the electromagnetic field components of the incident beam and the possibility of the formation of Laguerre-Gaussian mode.

Bound states in the continuum and high-Q resonances supported by a dielectric ridge on a slab waveguide
We investigate the diffraction of guided modes of a dielectric slab waveguide on a simple integrated structure consisting of a single dielectric ridge on the surface of the waveguide. Numerical…
Analysis of quasiperiodic and geometric optical solutions of the problem of focusing into an axial segment
An analytic and an iterative method for calculating novel quasiperiodic diffractive optical elements (DOEs) capable to focus the radiation into an optical axis segment are developed. A quasiperiodic…
Plasmon-mediated magneto-optical transparency
TLDR
A novel magneto-optical phenomenon that originates solely from suitably designed nanostructured metal-dielectric material, the so-called Magneto-plasmonic crystal, which allows manipulating and exciting waveguide modes by a magnetic field and light of proper polarization.
Planar two-groove optical differentiator in a slab waveguide.
TLDR
The presented numerical simulation results demonstrate high-quality spatial, temporal and the so-called spatiotemporal differentiation of optical pulses and beams propagating in the waveguide.
Extraordinary transmission and giant magneto-optical transverse Kerr effect in plasmonic nanostructured films
We predict a significant enhancement of the magneto-optical transverse Kerr effect when a smooth magnetic dielectric film is covered with a thin noble metal layer perforated with subwavelength slit…
