A versatile metasurface enabling superwettability for self-cleaning and dynamic color response
Jinlong Lu, Basudeb Sain, Philip Georgi +3
Metasurfaces provide applications for a variety of flat elements and devices due to the ability to modulate light with subwavelength structures. The working principle meanwhile giv…
Observing 0D subwavelength-localized modes at ~100 THz protected by weak topology
Jinlong Lu, Konstantin G. Wirth, Wenlong Gao +4
Topological photonic crystals (TPhCs) provide robust manipulation of light with built-in immunity to fabrication tolerances and disorder. Recently, it was shown that TPhCs based on…
Spin-Orbit Interaction of Light Enabled by Negative Coupling in High Quality Factor Optical Metasurfaces
Wenlong Gao, Basudeb Sain, Thomas Zentgraf
We study the negative couplings amid local resonances of photonic metasurfaces. In our analysis, we discover pseudo-spin-orbit coupled bulk modes leading to lines of circularly pol…
Efficient frequency conversion with geometric phase control in optical metasurfaces
Bernhard Reineke Matsudo, Basudeb Sain, Luca Carletti +5
Metasurfaces have appeared as a versatile platform for miniaturized functional nonlinear optics due to their design freedom in tailoring wavefronts. The key factor that limits its…
A wavelength and polarization selective photon sieve for holographic applications
Daniel Frese, Basudeb Sain, Hongqiang Zhou +3
Optical metasurfaces are perfect candidates for the phase and amplitude modulation of light, featuring an excellent basis for holographic applications. In this work, we present a d…
Optical secret sharing with cascaded metasurface holography
Philip Georgi, Qunshuo Wei, Basudeb Sain +4
Secret sharing is a well-established cryptographic primitive for storing highly sensitive information like encryption keys for encoded data. It describes the problem of splitting a…
