title: Long-period gratings in chalcogenide fibers.
abstract: We report the first demonstration of long period gratings in single mode As(2)Se(3) chalcogenide glass fiber. The grating is implemented by pressing a threaded rod against a short piece of fiber. Its strength can be tuned over a 25 dB range, has high repeatability, and is fully reversible.
