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