Known as Selerion-HTX&#x2122; commercially and HLD in scientific literature, this material redefines the boundaries of photonic performance, balancing a high EO coefficient (r<sub>33<\/sub>) and index of refraction with unprecedented long-term temperature stability for a hybrid OEO material. Selerion-HTX is the first material in NLM\u2019s Selerion family of hybrid OEO technologies. &nbsp;<\/p>\n\n\n\n<figure class=\"wp-block-gallery has-nested-images columns-default is-cropped wp-block-gallery-1 is-layout-flex wp-block-gallery-is-layout-flex\">\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"300\" height=\"100\" data-id=\"4357\" src=\"https:\/\/www.nlmphotonics.com\/wp-content\/uploads\/2025\/03\/selerion-final-300.png\" alt=\"\" class=\"wp-image-4357\"\/><\/figure>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"342\" data-id=\"3992\" src=\"https:\/\/www.nlmphotonics.com\/wp-content\/uploads\/2024\/10\/PoweredbyCoMotionlogo-1024x342.jpg\" alt=\"W (from University of Washington logo) Powered by CoMotion with a purple background\" class=\"wp-image-3992\" srcset=\"https:\/\/www.nlmphotonics.com\/wp-content\/uploads\/2024\/10\/PoweredbyCoMotionlogo-1024x342.jpg 1024w, https:\/\/www.nlmphotonics.com\/wp-content\/uploads\/2024\/10\/PoweredbyCoMotionlogo-300x100.jpg 300w, https:\/\/www.nlmphotonics.com\/wp-content\/uploads\/2024\/10\/PoweredbyCoMotionlogo-768x256.jpg 768w, https:\/\/www.nlmphotonics.com\/wp-content\/uploads\/2024\/10\/PoweredbyCoMotionlogo-1536x512.jpg 1536w, https:\/\/www.nlmphotonics.com\/wp-content\/uploads\/2024\/10\/PoweredbyCoMotionlogo.jpg 2000w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n<\/figure>\n\n\n\n<p class=\"\">The patent, \u201cCrosslinkable Nonlinear-Optical Chromophore System,\u201d was issued to the University of Washington under U.S. patent number 12187827 on January 7, 2025, and is exclusively licensed to NLM Photonics via CoMotion, UW\u2019s collaborative innovation hub. The patent protects the characteristics and methods of production for Selerion-HTX, as well as its applications in EO modulators and other devices.&nbsp;<\/p>\n\n\n\n<p class=\"\">Selerion-HTX exhibits performance characteristics including:&nbsp;<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li class=\"\"><strong>EO Coefficient: <\/strong>150 \u2013 450 pm\/V&nbsp;&nbsp;<\/li>\n\n\n\n<li class=\"\"><strong>Index of Refraction: <\/strong>1.75 \u2013 2.0 (wavelength dependent)&nbsp;<\/li>\n\n\n\n<li class=\"\"><strong>Poling efficiency:<\/strong> 2 \u2013 4 nm<sup>2<\/sup>\/V<sup>2<\/sup>&nbsp;<\/li>\n\n\n\n<li class=\"\"><strong>Thermal stability: <\/strong>In excess of 120 degrees Celsius long-term storage and operational stability&nbsp;<\/li>\n<\/ul>\n\n\n\n<p class=\"\">These capabilities contribute to a uniquely high figure of merit, validating the applicability of hybrid OEO materials in commercial applications ranging from data center communications to emerging quantum technologies. Crucially, this thermoset technology is compatible with current silicon manufacturing lines, enabling fabricators to incorporate Selerion-HTX into existing process flows with minimal disruption.&nbsp;<\/p>\n\n\n\n<p class=\"\">\u201cThe ability to sustain strong electro-optic activity at high temperatures marks a paradigm shift in how integrated photonic components are designed,\u201d said Dr. Delwin Elder, Director of Materials Development at NLM Photonics and co-inventor on the patent. \u201cSelerion-HTX will enable device manufacturers to move beyond the traditional performance and reliability tradeoffs of polymer and silicon-based technology, accelerating the deployment of truly next-generation EO components.\u201d&nbsp;<\/p>\n\n\n\n<p class=\"\">By combining an exceptional electro-optic response with robust thermal and operational stability, Selerion-HTX extends the frontiers of modulators, switches, and other EO devices that demand long-lasting, high-performance materials.
