Bend Waveguides on Silicon Nanowire Optical Waveguide (SNOW)
IEEE Photonics Journal, 2011 In a previous work, we reported a novel optical waveguide named silicon nanowire optical waveguide (SNOW), which consists of arrayed silicon nanowires acting like an effective-index medium.

Sub‐THz Phase Shifters Enabled by Photoconductive Single‐Walled Carbon Nanotube Layers
Advanced Photonics Research, 2023 Materials with tunable dielectric properties are highly relevant for terahertz (THz) applications. Herein, the tuning of the dielectric response of single‐walled carbon nanotube layers by light illumination is studied for applications to THz phase ...

Difference frequency generation by quasi-phase matching in periodically intermixed semiconductor superlattice waveguides [PDF]
, 2011 Wavelength conversion by difference frequency generation is demonstrated in domain-disordered quasi-phase-matched waveguides. The waveguide structure consisted of a GaAs/AlGaAs superlattice core that was periodically intermixed by ion implantation.

Advanced Functional Materials, EarlyView.We propose a suture‐complementary approach that integrates optical skin clearing with a strain‐programmable luminescent adhesive patch. Hyaluronic acid promotes transdermal delivery of tartrazine to improve optical clearing and stabilizes its interaction with a photosensitizer. Optical clearing increases the penetration depth of visible light into skin,

Inverse scattering designs of dispersion-engineered single-mode planar waveguides [PDF]
We use an inverse-scattering (IS) approach to design single-mode waveguides with controlled linear and higher-order dispersion. The technique is based on a numerical solution to the Gelfand-Levitan-Marchenko integral equation, for the inversion of ...

Demonstration of second harmonic generationin gallium phosphide nano-waveguides [PDF]
, 2020 We designed, fabricated and tested gallium phosphide (GaP) nano-waveguides for second harmonic generation (SHG). We demonstrate SHG in the visible range around 655 nm using low power continuous-wave pump in the optical communication O-band.
