- ПубликацияТолько метаданныеSuperperiodic Liquid-Crystal Metasurfaces for Electrically Controlled Anomalous Refraction(2020) Kasyanova, I. V.; Artemov, V. V.; Ezhov, A. A.; Mamonova, A. V.; Gorkunov, M. V.; Горкунов, Максим Валерьевич© 2020 American Chemical Society. All rights reserved.Optical liquid-crystal metasurfaces self-assemble on polymer layers locally processed with a digitally controlled focused ion beam. We expand their functionality by introducing superperiodic design consisting of parallel stripes of various widths inducing different liquid crystal alignment. We optimize the design to achieve strongly asymmetric light diffraction effectively resulting in efficient anomalous refraction. By implementing the optimal patterns of different periodicity, assembling a liquid crystal cell, and assessing its diffractive properties, we experimentally confirm the deflection of normally incident light into a particular oblique direction with 60% efficiency. Applying AC voltage of several volts amplitude across the liquid crystal reversibly straightens its orientation, suppresses the refraction, and reroutes light into the direct transmission. Time-resolved measurements reveal that the switching between refracting and transmitting states occurs within a few milliseconds in both directions.

We study the electro-optical switching from diffraction to transmission mode and show that it occurs within milliseconds.
- ПубликацияТолько метаданныеNonlinear diffraction of light on near-surface microdomain structures(2019) Kondratov, A. V.; Gorkunov, M. V.; Горкунов, Максим Валерьевич© 2019 Kvantovaya Elektronika and Turpion Ltd The nonlinear diffraction on periodic microdomain structures with different orientations of the spontaneous polarisation axis relative to the surface is theoretically considered. The possibility of reliable non-destructive diagnostics of the period, duty cycle and depth of domain structures, as well as of the shape of the domain walls under the crystalline surface is shown.
- ПубликацияТолько метаданныеCorrugated silicon metasurface optimized within the Rayleigh hypothesis for anomalous refraction at large angles(2019) Antonov, A. A.; Gorkunov, M. V.; Горкунов, Максим Валерьевич© 2019 Optical Society of America.We optimize the performance of optical metasurfaces based on periodically corrugated silicon layers by adjusting the Fourier coefficients of their surface profiles. For smooth corrugations, we demonstrate the excellent quantitative accuracy of a semi-analytical approach based on the Rayleigh hypothesis. We employ this approach to design metasurfaces with anomalous refraction due to dominant first-order diffraction. Unlike conventional Huygens’ dielectric metasurfaces, corrugated silicon layers are capable of efficient anomalous refraction in near-grazing directions: we obtain corrugation shapes allowing us to deflect 70%–80% of the energy of normally incident green light into the range of 68°–85° of angles with respect to the normal.
- ПубликацияТолько метаданныеLiquid crystal metasurfaces for versatile electrically tunable diffraction(2022) Mamonova, A. V.; Simdyankin, I. V.; Kasyanova, I. V.; Artemov, V. V.; Geivandov, A. R.; Palto, S. P.; Ezhov, A. A.; Gorkunov, M. V.; Горкунов, Максим ВалерьевичLiquid crystal (LC) metasurfaces self-assemble on polymer alignment layers patterned by focused ion beam inducing micrometre and submicrometre scale modulations of LC director imparting specific wavefront profiles to the transmitted light required for versatile optical functionalities. We report on the design, optimisation, fabrication and characterisation of LC metasurfaces performing as Dammann gratings distributing light uniformly in many diffraction channels. Comparing them with the previously reported diffracting and beam-steering LC metasurfaces, we demonstrate how the same approach can be applied to create photonic devices with qualitatively different diffraction properties switchable between diffracting and transparent states by low voltage within several milliseconds. Analysing the achievements, we elucidate the future potential of the LC metasurface concept and discuss particular application prospects. © 2022 Informa UK Limited, trading as Taylor and Francis Group.
- ПубликацияТолько метаданныеNon-Mechanical Multiplexed Beam-Steering Elements Based on Double-Sided Liquid Crystal Metasurfaces(2022) Gorkunov, M. V.; Geivandov, A. R.; Mamonova, A. V.; Simdyankin, I. V.; Ezhov, A. A.; Artemov, V. V.; Горкунов, Максим ВалерьевичWe propose, optimize, fabricate and test beam-steering elements based on double-sided liquid-crystal (LC) metasurfaces allowing for diffractive and spectral multiplexing, and thus covering three different beam deflection directions each. While straightforward parallel design requires one diffractive beam-steering element per a direction determined by Bragg’s law, double-sided LC-metasurfaces are remarkably flexible and allow optimization for three operation modes at different applied voltages: zero-voltage mode with dominant +1 order red light and +2 order blue light diffraction intermediate mode at 1.4–1.6 V voltage with dominant +1 order blue light diffraction and transparent mode at 5 V voltage. We comprehensively study three such elements with 6, 8 and 10 micrometer periods and verify their capability of deflecting blue and red light beams with 40–70% efficiencies in nine target directions with 10 ms characteristic switching times.
- ПубликацияТолько метаданныеDouble-sided liquid crystal metasurfaces for electrically and mechanically controlled broadband visible anomalous refraction(2022) Gorkunov, M. V.; Mamonova, A. V.; Kasyanova, I. V.; Ezhov, A. A.; Artemov, V. V.; Simdyankin, I. V.; Geivandov, A. R.; Горкунов, Максим ВалерьевичLiquid crystals self-assemble on nanopatterned alignment layers into purely soft matter metasurfaces sensitive to external stimuli and imparting tailored spatial modulations to transmitted light wavefronts. Upon fine optimization, they are capable of efficient light deflection by virtue of anomalous refraction into a dominating transmission diffraction order. To expand the spectral range and acquire additional functionality, we put forward the double-sided metasurface design based on the liquid crystal alignment by a pair of complementing patterned substrates. We numerically optimize, fabricate, and experimentally characterize metasurfaces refracting red light with an efficiency of up to 70% and sustaining the efficiency above 50% in a broad range of visible wavelengths exceeding 500 nm. We verify that the refraction is reversibly switched in less than 10 ms by voltages of a few volts. We also report on a remarkable mechanical reconfigurability, as micrometer-scale relative substrate shift flips the refraction direction. © 2022 the author(s), published by De Gruyter, Berlin/Boston.
