Abstract

Provided are a device and method for fabricating an optical fiber Bragg grating, comprising a laser device, a laser shaping device, a laser interference device, a clamping movable device, and an organic-solution filling device; a liquid filling port of the clamping movable device is connected to the output port of the organic-solution filling device; the laser device emits laser light to the laser shaping device; the laser shaping device shapes the laser light, then transmits it to the laser interference device; the laser interference device splits the laser into two laser beams; the two laser beams interfere and periodically distributed laser interference fringes are obtained; the organic-solution filling device fills and attaches the organic solution to the surface of the inner wall of an hollow-core fiber; the clamping movable device moves the hollow-core fiber.
