Title: Method for developing fiber grating and fiber grating
Inventor: IMAMURA KAZUO
IPC: G02B5/18
Filed: 2001-04-13
Abstract: PROBLEM TO BE SOLVED: To provide a novel method for developing fiber grating, with which a grating structure is developed not only on a core but also on a clad or coat layer stably for a long time, and such a fiber grating. SOLUTION: The state of a standing wave is provided by impressing an ultrasonic wave to a medium surrounding an optical fiber. The medium is made into dense part 21 and coarse part 22 by the ultrasonic wave and pressure in the dense part 21 is higher than pressure in the coarse part 22. Therefore, an optical fiber dense part 23 in contact with the medium dense part 21 is compressed and improves density rather than an optical fiber coarse part 24 in contact with the medium coarse part 22. Thus, the refraction factor of the optical fiber dense part 23 becomes higher than that of the optical fiber coarse part 24 and the grating structure is formed over the entire optical fiber.
