Previously known as NP Photonic Technologies LLC, NP Photonics develops and manufactures specialty fiber lasers, fiber amplifiers and transport fibers for the near- and mid-infrared (IR) wavelength bands. The firm's proprietary fiber technology is used across a broad family of products, including narrow linewidth, low phase-noise fiber lasers designed for operation in industrial environments. The firm currently has over thirty patents, which mainly relate to glass composition, glass processing, fiber manufacturing, splicing, fiber lasers, fiber components and fiber amplifiers, all at multiple wavelengths across the near- and mid-IR. The firms core technologies are founded on innovations in proprietary specialty phosphate, germanate, and tellurite glasses, which are a key enabler in the firms fiber-based lasers, amplifiers and ASE sources. At the heart of these lasers and amplifiers is an active fiber, which is most commonly made of silica host glass. However, the ability to dope silica glass fibers with high concentrations of rare earth ions, such as erbium, ytterbium, thulium, and holmium is limited due to effects that degrade gain fiber efficiency. As an alternative, NP Photonics has developed highly doped phosphate glass fibers that are up to a hundred times greater than in silica without any negative effect to the optical gain, enabling a variety of optical devices that make use of high optical gain in a short length.
