Journal ArticleDOI
Chalcogenide Hybrid Inorganic/Organic Polymers: Ultrahigh Refractive Index Polymers for Infrared Imaging
Laura E. Anderson,Tristan S. Kleine,Yueyan Zhang,David D. Phan,Soha Namnabat,Edward Anthony LaVilla,Katrina M. Konopka,Liliana Ruiz Diaz,Michael S. Manchester,Jim Schwiegerling,Richard S. Glass,Michael E. Mackay,Kookheon Char,Robert A. Norwood,Jeffrey Pyun,Jeffrey Pyun +15 more
TL;DR: In this paper, the authors reported the preparation of ultrahigh refractive index polymers via the inverse vulcanization of elemental sulfur, selenium, and 1,3-diisopropenylbenzene for use as novel transmissive materials for mid-infrared (IR) imaging applications.
PatentDOI
Athermal silicon optical add-drop multiplexers based on thermo-optic coefficient tuning of sol-gel material
TL;DR: Curing time compared to curing temperature shows to be the most important factor to control sol-gel's thermo-optic value in order to obtain an athermal device in a wide temperature range.
