Ink-jetting AJL8/APC for D-fiber electric field sensors

Abstract

Spin casting electro-optic polymers for in-fiber device fabrication is problematic due to the flexibility and high-contrast topography of optical fibers. An ink-jetting method is developed for the deposition of AJL8/APC using a commercially available printer. The method results in more consistent control of film thickness and uses 1000 times less material than the spin-coating method. A D-fiber electric field sensor is fabricated using this deposition method and exhibits a sensitivity of 157 V/(m square root(Hz)) at a modulation frequency of 6 GHz.

Smart Window Structures Based on Highly Conductive, Transparent Metal Nanomeshes and Thermochromic Perovskite Films

“…[ 10 ] In addition, the relatively low thermal conductivity of ITO leads to longer response times for devices reliant on thermally activated transitions, such as thermochromic smart windows. Extensive research has therefore been devoted to ITO alternatives including carbon‐based TCEs such as graphene, [ 11 ] carbon nanotubes, [ 12 ] or conducting polymers, [ 13 ] and metal‐based TCEs such as metal nanowires [ 14 ] or metal meshes. [ 15 ] Among these ITO alternatives, metal meshes, which are composed of periodic micro‐ or nanostructured metal networks on a transparent substrate, have gained considerable attention as high performance TCEs offering several advantages, including excellent mechanical flexibility, high conductivity, tunable transmittance, and low fabrication cost.…”
