Analysis of Waveguides on Lithium Niobate Thin Films

open access: yesCrystals, 2018
Waveguides formed by etching, proton-exchange (PE), and strip-loaded on single-crystal lithium niobate (LN) thin film were designed and simulated by a full-vectorial finite difference method.

Optical characteristics of an oxyfluoride glass waveguide formed by a proton implantation

open access: yesResults in Physics, 2018
An optical waveguide was fabricated by H+ ion implantation with an energy of 400 keV and a dose of 8 × 1016 ions/cm2 in the oxyfluoride glass for the first time to the best of our knowledge. The dark mode spectra of the waveguide were measured by a prism

Strain‐Programmable Luminescent Adhesive Patch With Tartrazine‐Mediated Optical Skin Clearing for Photochemical Tissue Bonding

open access: yesAdvanced 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,
