Asymmetric Fabry-Perot-type transmission in photonic-crystal gratings with one-sided corrugations at a two-way coupling

Serebryannikov, A. E.; Alici, K. B.; Magath, T.; Cakmak, A. O.; Ozbay, E. (American Physical Society, 2012-11-29)

Strongly asymmetric Fabry-Perot-type transmission arising at the two-way coupling has been studied in the case of normal incidence for slabs of two-dimensional photonic crystals (PCs) with one-sided corrugations that are ...

Asymmetric transmission in prisms using structures and materials with isotropic-type dispersion

Gundogdu, F. T.; Serebryannikov, A. E.; Cakmak, A. O.; Ozbay, E. (Optical Society of America, 2015)

It is demonstrated that strong asymmetry in transmission can be obtained at the Gaussian beam illumination for a single prism based on a photonic crystal (PhC) with isotropic-type dispersion, as well as for its analog made ...

Chiral metamaterials: From negative index to asymmetric transmission

Mutlu, M.; Li, Z.; Ozbay, Ekmel (2013)

Chiral metamaterials are attractive for their intriguing properties such as negative refractive index, optical activity and circular dichroism, and asymmetric transmission. In this paper, we review the research we have ...

Dielectric inspired scaling of polarization conversion subwavelength resonances in open ultrathin chiral structures

Serebryannikov, A. E.; Mutlu, M.; Ozbay, E. (A I P Publishing LLC, 2015)

It is shown that the scaling of subwavelength resonances in open ultrathin chiral structures can be obtained by varying only the permittivity of dielectric spacers, while multiband one-way polarization conversion and related ...

Diffraction inspired unidirectional and bidirectional beam splitting in defect-containing photonic structures without interface corrugations

Colak, E.; Serebryannikov, A. E.; Usik, P. V.; Ozbay, E. (American Institute of Physics Inc., 2016)

It is shown that strong diffractions and related dual-beam splitting can be obtained at transmission through the nonsymmetric structures that represent two slabs of photonic crystal (PhC) separated by a single coupled-cavity ...

Diodelike asymmetric transmission of linearly polarized waves using magnetoelectric coupling and electromagnetic wave tunneling

Mutlu, M.; Akosman, A. E.; Serebryannikov, A. E.; Ozbay, E. (American Physical Society, 2012-05-24)

An asymmetric, reciprocal, diffraction-free transmission of linearly polarized waves in a new diodelike, three-layer, ultrathin, chiral structure is studied theoretically and experimentally. The exploited physical mechanism ...

Dispersion irrelevant wideband asymmetric transmission in dielectric photonic crystal gratings

Serebryannikov, A. E.; Colak, E.; Cakmak, A. O.; Ozbay, E. (Optical Society of America, 2012-11-22)

Wideband suppression of zero order and relevant strongly asymmetric transmission can be obtained in photonic crystal gratings that are made of linear isotropic materials and show the broken structural (axial) symmetry, ...

Highly asymmetric transmission of linearly polarized waves realized with a multilayered structure including chiral metamaterials

Li, Z.; Mutlu, M.; Ozbay, E. (IOP Publishing, 2014)

We numerically and experimentally demonstrate highly asymmetric transmission of linearly polarized waves with a multilayered metallic structure. The whole structure has a subwavelength thickness and consists of a thin slab ...

Multiband one-way polarization conversion in complementary split-ring resonator based structures by combining chirality and tunneling

Serebryannikov, A. E.; Beruete, M.; Mutlu, M.; Ozbay, E. (OSA - The Optical Society, 2015)

Multiband one-way polarization conversion and strong asymmetry in transmission inspired by it are demonstrated in ultrathin sandwiched structures that comprise two twisted aperture-type arrays of complementary split-ring ...
