Arbor Photonics of Ann Arbor, Mich., has signed an exclusive license agreement for chirally-coupled core optical fiber with the University of Michigan. The agreement grants Arbor Photonics rights to commercialize the fiber and devices enabled by the innovative design for lasers, optical amplifiers and laser beam delivery. The chirally-coupled core concept, dubbed "CCC" or "3C" fiber, is an optical fiber that utilizes an internal structure to produce single spatial mode output from very large mode area fibers, and was invented by Almantas Galvanauskas, professor at the University of Michigan Center for Ultrafast Optical Science. According to Arbor Photonics, the 3C fiber technology will boost performance in terms of average power, peak power and brightness and will benefit laser applications in microelectronics, solar cell manufacturing and defense.
