Additive and Subtractive Color Filters Based on Birefringent Dielectric Metasurfaces
Ondřej Červinka, Filip Ligmajer, Ondřej Brunn +3
Dielectric metasurfaces offer a path to high-efficiency optical components at the sub-wavelength scale. In this work, we utilize the wavelength-dependent birefringence of TiO2 nano…
Inverse designed full-Stokes polarimetric metasurface with simultaneous wavefront sensing for visible light
Ondřej Červinka, Martin Hrtoň, Štěpán Venos +4
Metasurfaces have emerged as a powerful platform for compact optical sensors by replacing bulky lenses with flat arrays of subwavelength nanostructures. In precision optical metrol…
Active Loss Engineering in Vanadium Dioxide Based BIC Metasurfaces
Andreas Aigner, Filip Ligmajer, Katarína Rovenská +5
Metasurfaces have unlocked significant advancements across photonics, yet their efficient active control remains challenging. The active materials required often lack continuous tu…
Structural color filters with compensated angle-dependent shifts
Katarína Rovenská, Filip Ligmajer, Beáta Idesová +4
Structural color filters use nano-sized elements to selectively transmit incident light, offering a scalable, economical and environmentally friendly alternative to traditional pig…
