IRflex Corporation Awarded DOD SBIR Phase I contract for High Performance Optical Fibers for 100-Watts infrared Lasers.

November 24, 2020, Danville, VA – Rflex Corporation, has been awarded a United States Department of Defense Small Business Innovation Research (SBIR) Contract entitled High Performance Optical Fibers for 100-Watts infrared Lasers.

The objective of this contract is to develop a high performance, low loss (less than 0.5dB/m), infrared (IR) fiber technology for transmitting high power greater than 100 Watts CW from a multi-band mid-infrared laser for the wavelength from 2 to 6 micron. The Phase 1 contract is to design an approach to produce such fiber using our chalcogenide glass fiber technology and performance assessment.

The period of performance for this effort is six months from December 1, 2020 to May 31, 2021.  A four months option is included as a possible bridge option between Phase 1 and Phase 2.

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.
