Abstract
Disclosed is a device for fabricating a polarization insensitive long-period fiber grating which includes: an ultraviolet laser for irradiating a ultraviolet laser beam; an ultraviolet polarizer for converting a polarization status of the ultraviolet laser beam into a linear polarization status in parallel along the longitudinal direction of a fiber; a lens for adjusting a focus of the ultraviolet laser beam from the ultraviolet polarizer; an amplitude mask for selectively passing the ultraviolet laser beam from the lens; and, a mount for holding both ends of the fiber so that the outer circumferential surface of the fiber can be exposed to the ultraviolet laser beam from the amplitude mask.
