Optical Control of Chirality by Ultrafast Symmetry Breaking in Membrane Metasurfaces
Nikita Glebov, Alena Mamonova, Olesia Pashina +7
Chirality underpins a wide range of light-matter interactions, yet methods for its dynamic control in photonic systems remain limited. Here, we demonstrate ultrafast all-optical co…
Metasurface-Enhanced Mid-Infrared Imaging Spectroscopy with Broadband Quantum Cascade Lasers
Ivan Sinev, Alessio Cargioli, Diego Piciocchi +3
Mid-infrared (mid-IR) spectroscopy offers unparalleled opportunities in sensing through chemically specific detection of molecular absorption fingerprints. Yet, its practical appli…
Nonlinear chiral response governed by meta-atom rotation
Dhruv Hariharan, Pavel Tonkaev, Felix Ulrich Brikh +5
Chiral photonics provides powerful routes for controlling the light handedness, yet nonlinear chiral responses are typically associated with intricate three-dimensional systems. He…
Mid-IR Light Modulators Enabled by Dynamically Tunable Ultra High-Q Silicon Membrane Metasurfaces
Felix Ulrich Brikh, Aleksei Ezerskii, Olesia Pashina +6
Metasurfaces have emerged as a powerful platform to control free-space light at the subwavelength scale, enabling applications in sensing, lasing, nonlinear optics, and quantum pho…
