Robust Photonic Quantum Gates With A Large Number of Waveguide Segments

Advanced Quantum Technologies, EarlyView.
This study investigates segmented waveguide designs for photonic quantum gates, extending existing composite approaches to a large number of segments. Through numerical simulations, the work analyzes fidelity, power loss, and the effect of noise correlations.

Acousto-Plasmonic Sensing Assisted by Nonlinear Optical Interactions in Bimetallic Au-Pt Nanoparticles

Micromachines, 2017
A strong influence of mechanical action in nonlinear optical transmittance experiments with bimetallic nanoparticles integrated by gold and platinum was observed. The nanostructured samples were synthesized by a sol-gel method and contained in an ethanol

Design of a broadband acousto-optic filter using bulk acoustic wave beam steering with an interdigital transducer

Results in Physics
Acousto-optic tunable filters are photonics devices whose operation is fundamentally based on crystal acoustics. One of the phenomena used to improve performances of bulk acousto-optic devices is acoustic beam steering.

Topological Polaritonic Metamaterials Realized in Bulk Transition Metal Dichalcogenide Crystals

Small Structures, EarlyView.
Monolithic all‐van der Waals materials‐based polaritonic topological insulators are introduced and demonstrated that support robust boundary modes for extreme confinement and robust propagation of strongly coupled exciton‐photon hybrid particles, which are readily tunable with temperature. These monolithic polaritonic topological metasurfaces can serve
