IRflex granted Patent for Hollow-Core with Anti-Resonant Arches (HC-ARA) Fiber and Method of Manufacturing Thereof

IRflex Corporation proud to announce that on October 27, 2020, the United States Patent and Trademark Office has issued Patent Number: US 10, 816, 721 B1 to IRflex Corporation for Hollow-Core Fiber with Anti-Resonant Arches and Method of Manufacturing Thereof for the protection of this corporate product invention and intellectual property.

Innovation can change the world, thanks to this prestigious award to help recognize such an important achievement.

The embodiments of this patent relate generally to the design and precise fabrication of a hollow-core anti-resonant arches  (HC-ARA) fiber, and more particularly to a hollow-core fiber made from an extruded soft glass preform that utilizes a single layer of robust reflecting optical arches for transmission of mid-to long-infrared wavelengths (1-15 micron).  The guidance mechanism and design of this fiber allow the low-loss transmission of wavelengths of light which falls within the high absorption spectrum of the confining material.

IRflex is currently working on the HC-ARA fiber using our chalcogenide glass for the CO2 laser transmission at 10.6 micron.
