Self-Action of Structured Light Beams in Amorphous Azobenzene-Containing Polymer

I.A. Budagovsky;M.P. Smayev;A.I. Baranov;A.A. Kuznetsov;A.S. Zolot’Ko;A.Yu. Bobrovsky

2024 International Conference Laser Optics (ICLO)

Year: 2024 | Conference Paper |

HTML

The action of the light beams of various structure and their transformation in a thin layer of the polymethacrylate azobenzene-containing polymer is studied. This material shows high optical nonlinearity related to trans-cis transitions of absorbing fragments, whose reorientation can induce optical anisotropy and affect refractive indices. Additional methyl groups provide higher sensitivity in the...Show More

Vortex-Generating Light-Induced Phase Converter in Azobenzene Polymer

I.A. Budagovsky;M.P. Smayev;A.S. Zolot’Ko;A.Yu. Bobrovsky

2024 International Conference Laser Optics (ICLO)

Year: 2024 | Conference Paper |

HTML

The formation of the modified area, which acts as phase converter for vortex generation, in the amorphous thin layer of the azo-containing polymer under the action of structured light beam is considered. The optical axes are produced in accordance with the polarization structure of the pump light beam. The beam with radial polarization induces the axially-symmetric optical axis distribution (simil...Show More

High Thermal Tunability of Optical Transmission of Epsilon-Near-Zero Metamaterials Based on Nanorods in Liquid Crystals

V.B. Novikov;A.K. Zagravskii;S.V. Sotnichuk;N.K. Davidenko;A. Yu. Bobrovsky;K.S. Napolskii;T.V. Murzina

2024 International Conference Laser Optics (ICLO)

Year: 2024 | Conference Paper |

HTML

We experimentally and numerically revealed a salient thermal effect in the transmission of the epsilon-near-zero (ENZ) metamaterial consisting of an array of plasmonic nanorods in a dielectric template. The flavor of the structure is freestanding nanorod segments surrounded by nematic liquid crystals possessing a strong thermal dependence of the anisotropic refractive index. The observed resonant ...Show More

2016 International Conference Laser Optics (LO)

Year: 2016 | Conference Paper |

HTML

The Zernike method using a nematic liquid crystal (NLC) filter with orientational optical nonlinearity was applied to visualize phase objects. It was shown that the contrast sign of the image switches by means of varying the incidence angle of a light beam on liquid crystal cell. The comparison of a contrast sign change of opaque object in the schemes based on NLC-filter and on liquid filter with ...Show More

2016 International Conference Laser Optics (LO)

Year: 2016 | Conference Paper |

HTML

Optical nonlinearity of nematic liquid crystalline polymer caused by molecular reorientation was found and investigated. Under the action of light on the polymer film, director of polymer reorients to light field increasing the refractive index. If the polymer is doped with an azobenzene compound, nonlinear response dramatically increases; in this case, the light-induced refractive index becomes n...Show More
