In this study, we both numerically and experimentally present a metasurface (MS) polarization converter to transform linearly polarized signal into circularly polarized one. The unit cell consists of two rectangular metallic patches placed at the crossed corners of rectangularly arranged inclusions. The results of a full-wave Electromagnetic (EM) simulator are compared to those of free space measurement using two horn antenna at microwave frequency regime. For a linearly polarized antenna, the s-parameters are obtained for both co-polarized and cross-polarized responses. The polarization quality referred to as axial ratio (AR) is expressed by the ratio of these two responses. It is found that, strong polarization conversion activity is obtained with the proposed MS at the frequency of about 3 GHz. As a result, we can generate polarization converter with a wide bandwidth, of interest for microwave filtering, coating, and especially polarization conversion devices. (C) 2018 Elsevier GmbH.

Engineering nonlinear response of nanomaterials using Fano resonances Turkpence, Deniz; Akguc, Gursoy B.; Bek, Alpan; Taşgın, Mehmet Emre (IOP Publishing, 2014-10-01) We show that nonlinear optical processes of nanoparticles can be controlled by the presence of interactions with a molecule or a quantum dot. By choosing the appropriate level spacing for the quantum emitter, one can either suppress or enhance the nonlinear frequency conversion. We reveal the underlying mechanism for this effect, which is already observed in recent experiments: (i) suppression occurs simply because transparency induced by Fano resonance does not allow an excitation at the converted frequenc...
Demonstration of optical nonlinearity in InGaAsP/InP passive waveguides Saeidi, Shayan; Rasekh, Payman; Awan, Kashif M.; Tugen, Alperen; Huttunen, Mikko J.; Dolgaleva, Ksenia (Elsevier BV, 2018-10-01) We report on the study of the third-order nonlinear optical interactions in InxGa1-xAsyP1-y/InP strip-loaded waveguides. The material composition and waveguide structures were optimized for enhanced nonlinear optical interactions. We performed self-phase modulation, four-wave mixing and nonlinear absorption measurements at the pump wavelength 1568 nm in our waveguides. The nonlinear phase shift of up to 2.5 pi has been observed in self-phase modulation experiments. The measured value of the two-photon absor...
Optical parameters of anisotropic chain-structured Tl2InGaTe4 crystals by spectroscopic ellipsometry IŞIK, MEHMET; Hasanlı, Nızamı (Elsevier BV, 2016-01-01) Spectroscopic ellipsometry measurements were performed on Tl2InGaTe4 single crystals in the 1.2-6.2 eV range for orientations of electric field, parallel (E//c) and perpendicular (E perpendicular to c) to optic axis c. Spectral dependence of optical parameters; real and imaginary components of the dielectric function, refractive index and extinction coefficient were obtained from the analyses of experimental data using an ambient-substrate optical model. The analysis of the absorption data calculated using ...
Characterization of chiral metamaterial sensor with high sensitivity Dalgac, Sekip; BAKIR, MEHMET; KARADAĞ, FARUK; ÜNAL, EMİN; KARAASLAN, MUHARREM; Sabah, Cumali (Elsevier BV, 2020-02-01) In this study, a chiral metamaterial sensor applications are created by placing asymmetrically two meander line front and back side of the substrate layer. Characterization of the dielectric constant, thickness and loss tangent have been performed both in simulation and experimental methods. Different Arlon type materials used for showing the effects of dielectric constant on transmission coefficient. Obtained bandwidths for characterization are greater than the similar studies which verifyies increased sen...
Nonlinear optical properties of a Woods-Saxon quantum dot under an electric field AYTEKİN, ÖZLEM; Turgut, Sadi; Unal, V. Ustoglu; Aksahin, E.; Tomak, Mehmet (Elsevier BV, 2013-12-01) A theoretical study of the effect of the confining potential on the nonlinear optical properties of two dimensional quantum dots is performed. A three-parameter Woods-Saxon potential is used within the density matrix formalism. The control of confinement by three parameters and an applied electric field gives one quite an advantage in studying their effects on the nonlinear properties. The coefficients investigated include the optical rectification, second and third-harmonic generation and the change in the...
