Fabrication of tilted long-period fiber gratings by CO2 laser

We demonstrated experimentally the fabrication of tilted long-period fiber gratings (LPFGs) with different tilt angles by CO2 laser. The experiment results reveal that the LPFGs written with different tilt angles have quite different transmission spectra, the polarization sensitive LPFGs can be written with large tilt angles by the CO2 laser.
