Herein, we offer a numerical study on the devising of unique 2D-heterostructure photonic crystal (PC) that can split two orthogonally polarized light waves. The analysis is performed via two-dimensional finite element method (2D-FEM) by utilizing COMSOL Multiphysics software. device consists discrete designs PC formation. first formation optimized so it permits both TE- and TM-polarization to t...

We introduce a novel polarizing beam splitter that uses the anisotropic spectral reflectivity (ASR) characteristics of a high spatial frequency multilayer binary grating. By combining the form birefringence effect of a high spatial frequency grating with the resonant reflectivity of a periodic multilayer structure, the ASR characteristics for the two orthogonal linear polarizations are obtained...

We realize and experimentally characterize a novel platform for surface-enhanced sensing through Bloch Surface Waves (BSWs). test one-dimensional photonic crystal, with high index inclusion in the top layer, that sustains surfaces modes with, principle, arbitrary polarization. This is achieved coherent superposition of TE TM dispersion relations BSWs, which can also provide superchiral fields o...

Optical polarizing devices exploiting graphene embedded in waveguides have been demonstrated in the literature recently and both the TE- and TM-pass behaviors were reported. The determination of the passing polarization is usually attributed to graphene's Fermi level (and, therefore, doping level), with, however, no direct confirmation of this assumption provided. Here we show, through numerica...

In this work, we demonstrated metal tagged cell counting based on planar waveguide with the help of a visible light at 633 nm with TM polarization and calculated the output power in relation with the density of cells placed on the waveguide.

We show theoretically that polarization instability can be observed in planar optical waveguides. Such instability would lead to energy exchange between the spatial solitons associated with the TE(0) and TM(0) waveguide modes as well as to amplitude-modulation gain, which was recently observed in an optical-fiber geometry.

The $s,p-d$ exchange coupling between the spins of band carriers and transition metal (TM) dopants ranging from Ti to Cu in ZnO is studied within density functional theory. $+U$ corrections are included reproduce experimental gap dopant levels. $p-d$ reveals unexpectedly complex features. In particular, (i) constants $N_0\beta$ vary about 10 times when going V Cu, (ii) not only value but also s...

The performance of a chirped waveguide grating as a wavelength demultiplexer has been investigated. Considerations include TE-‘LX, TE-TM and TM-TM mode coupling for different incident angles and waveguide parameters. The spectral response of the chirped sinusoidal surface relief grating in the optical waveguide has been studied by means of Local Normal Mode Expansion (LNME) theory to account fo...

Mass spectrometry experiments show an exceptionally weak bonding between Si7Mn(+) and rare gas atoms as compared to other exohedrally transition metal (TM) doped silicon clusters and other SinMn(+) (n = 5-10) sizes. The Si7Mn(+) cluster does not form Ar complexes and the observed fraction of Xe complexes is low. The interaction of two cluster series, SinMn(+) (n = 6-10) and Si7TM(+) (TM = Cr, M...
