  • Abstract
    We apply a CO2 laser writing method to the fabrication of sophisticated long-period fiber grating (LPFG) filters. The method allows the position of the writing beam to be computer-programmed to produce the required grating profile without using any mask. We demonstrate the flexibility and the controllability of the method with a number of apodized phase-shifted LPFGs written in a germanium-boron codoped fiber.
