Optimized virtual optical waveguides enhance light throughput in scattering media [PDF]

open access: yesNature Communications, 2023
Ultrasonically-sculpted gradient-index optical waveguides enable non-invasive light confinement inside scattering media. The confinement level strongly depends on ultrasound parameters (e.g., amplitude, frequency), and medium optical properties (e.g ...

Liquid crystal tunable claddings for polymer integrated optical waveguides [PDF]

open access: yesBeilstein Journal of Nanotechnology, 2019
Optical waveguides in photonic integrated circuits are traditionally passive elements merely carrying optical signals from one point to another. These elements could contribute to the integrated circuit functionality if they were modulated either by ...

Toward the Development of Plasmonic Biosensors to Realize Point-of-Care Tests for the Detection of Viruses and Bacteria

open access: yesEngineering Proceedings, 2023
Optical fiber biosensors can be used to develop point-of-care tests (POCTs) for detecting viruses and bacteria in several matrices. In particular, the surface plasmon resonance (SPR) and localized SPR phenomena (LSPR) can be excited by exploiting low ...
