Reversible Laser Imprinting of Phase Change Photonic Structures in Integrated Waveguides

Ivan Sinev

Formation of laser-induced periodic surface structures (LIPSS) is known as a fast and robust method of functionalization of material surfaces. Of particular interest are LIPSS that manifest as periodic modulation of phase state of the material, as it impli ...

Spectral Tuning of High-Harmonic Generation with Resonance-Gradient Metasurfaces

Hatice Altug, Felix Ulrich Brikh, Ivan Sinev

High-index dielectric subwavelength structures and metasurfaces are capable of enhancing light-matter interaction by orders of magnitude via geometry-dependent optical resonances. This enhancement, however, comes with a fundamental limitation of a narrow s ...

Gradient High-Q Dielectric Metasurfaces for Broadband Sensing and Control of Vibrational Light-Matter Coupling

Hatice Altug, Aleksandrs Leitis, Felix Ulrich Brikh, Ivan Sinev, Senlu Zhou

Surface-enhanced infrared absorption spectroscopy (SEIRA) has emerged as a powerful technique for ultrasensitive chemical-specific analysis. SEIRA can be realized by employing metasurfaces that can enhance light-matter interactions in the spectral bands of ...

Plasmonic biosensor enabled by resonant quantum tunnelling

Hatice Altug, Ivan Sinev, Mikhail Masharin

Metasurfaces provide an ideal platform for optical sensing because they produce strong light-field confinement and enhancement over extended regions that allow us to identify deep-subwavelength layers of organic and inorganic molecules. However, the requir ...

Chirality encoding in resonant metasurfaces governed by lattice symmetries

Hatice Altug, Felix Ulrich Brikh, Ivan Sinev, Nikita Glebov

Chiral metasurfaces provide invaluable tools for controlling structured light required for biosensing, photochemistry, holography, and quantum photonics. Here we suggest and realize a universal strategy for engineering chiral response of resonant metasurfa ...
