A STTR Phase I contract was awarded to N.P. PHOTONICS, INC. in June, 2022 for $140,000.0 USD from the U.S. Department of Defense and United States Navy.
Fiber optical isolators with kilowatt power handling capability are in great demand for high-energy all-fiber laser systems. NP Photonics proposes to design and develop fiber optical isolators using our innovative fiber Faraday rotators and polarizers. The proposed fiber optical isolators have the advantages of high-power handling, compactness, and high reliability. In this Phase I program, we will investigate the feasibility and study the risk of developing kW-class fiber optical isolators based on innovative fiber designs. In Phase II, kW-class fiber optical isolators meeting or exceeding the requirements for submarine high energy laser amplifiers will be developed and tested.
