摘要
An apparatus and method used in manufacturing a long period grating filter are provided. The apparatus used in manufacturing a long period grating filter includes an upper body including a plurality of teeth spaced from each other by a predetermined distance and a lower body having teeth spaced from each other by the same distance as the teeth of the upper body and a plurality of grooves in a direction perpendicular to the teeth in which an optical fiber is loaded, wherein the upper and lower bodies are engaged with each other, and a plurality of grooves are formed in the loaded optical fiber by abrading the loaded optical fiber by moving the upper body in a direction parallel to the teeth. According to the present invention, an excimer laser, various other expensive equipment, and an optical fiber sensitive to ultraviolet rays are not required for manufacturing the long period grating filter. Accordingly, complicated hydrogen processing is not necessary. Also, stability to temperature is excellent, since the resultant filter is not obtained by changing the refractive index of the optical fiber.
