Researchers at BlazePhotonics Ltd. and at the University of Bath, both in Bath, UK, have fabricated a new low-loss photonic bandgap fiber. Its attenuation of 1.72 dB/km represents a significant improvement over the lowest loss previously reported for such a fiber, 13 dB/km. The development brings the attenuation of the new fibers a giant step closer to the ~0.15 dB/km of conventional telecom optical fibers and emphasizes their potential for long-haul data transmission. Unlike conventional optical fibers, photonic bandgap fibers do not guide light by total internal reflection but rely on a...Read full article
