Paper Abstract

Microstructured optical fibers are usually divided into two different types of fibers: solid-core photonic crystal fibers and air-core photonic bandgaps fibers. This paper presents long period fiber gratings written in both solid-core PCFs and aircore PBGs by use of a CO2 laser. A sensitive stain sensor was demonstrated by use of a CO2-laser-written long period fiber grating in a solid-core photonic crystal fiber. An in-fiber polarizer based on a long period fiber grating was written by use of a focused CO2 laser beam to notch periodically on a solid-core photonic crystal fiber. Moreover, a novel long period fiber grating was written in air-core photonic bandgap fibers by use of a CO2 laser periodically collapse air holes in the fiber cladding.
