Guiding Photonics produces hollow core fibers for mid-infrared lasers (e.g., quantum cascade lasers and interband cascade lasers) and for high power power lasers spanning the wavelength range from UV to far-IR. Guiding Photonics spun out of OptoKnowledge, which is a research and development company with a wide breadth of technologies focused on spectroscopy and imaging. Seizing on an opportunity to transition technology developed at Rutgers University, hollow fiber fabrication began at OptoKnowledge in 2012 and has steadily grown over the past 8 years. Guiding Photonics is built directly on this foundation and will continue to advance the state of the art and push the technology of low-loss, robust hollow fibers and associated components. This includes continued development of unique, proprietary plastic fibers, single-mode fibers, fiber bundles, and optical assemblies. All of the principals leading the fiber development at OptoKnowledge are part of the Guiding team and pledge to maintain the same high quality and unmatched customer service.
