IRflex Corporation Awarded NAVAIR SBIR Phase II contract for Mid-Wave Infrared Polarization-Maintaining Single Mode Fiber

IRflex Corporation, has been awarded a United States NAVAIR Small Business Innovation Research (SBIR) Contract entitled “Mid-Wave Infrared Polarization-Maintaining Single Mode Fiber”.  After successfully competing Phase I and Phase I Option contracts, IRflex Corporation was awarded Phase II contract with the same title.  The objective is to develop single mode polarization-maintaining fiber (PM-fiber) that covers the mid-wave infrared (MWIR) wavelengths from 2mm – 6mm for applications that require a high polarization extinction ratio at the fiber output and is able to waveguide tens of watts of optical power through the fiber.

Applications requiring linearly polarized light and flexibility of fiber delivery in the MWIR region will require a fiber solution that preserve the polarization state of the launched light.  Most infrared lasers are polarized.  PM-fiber offers the capability of preserving the launched light polarization state as it propagates through the fiber.  Commercially available silica PM-fibers cover the visible and near-infrared spectrum, currently there is no commercially available PM-fiber solution for the MWIR region.

Phase II: Develop an initial PM-fiber prototype.  Perform characterization of the optical and mechanical performance of the PM-fiber.  Compare experimental results to the expected specifications.

The Phase II contract will take place over the next twenty-four months.  The ultimate deliverable will be the demonstration of infrared polarization-maintaining fiber.  At that time, IRflex intends to pursue commercialization of the technology.

IRflex signed another SBIR Phase I contract with Army to develop additive nanostructures for broadband antireflectivity

On August 6, 2020 IRflex Corporation signed SBIR Phase I contract with Army for developing Additive Nanostructures for Broadband Antireflectivity in response to SBIR Topic No. A20-045.

The objective of this research project is to develop and deliver optical elements that minimize reflection and improve light transmission by the additive fabrication of nanostructured arrays.  The Fabrication of ANA should include growth methods for IR Lensing materials including Ge, ZnS, GaAs, and CaF2.
