Abstract:
The present embodiment relates to an MCF and the like suitable for fabricating an FBG with improved ripple characteristics. The MCF is mainly composed of silica glass, and comprises a plurality of light guiding structures and a common cladding. Each of the light guiding structures includes a core, a first cladding, and a second cladding. The refractive index of the second cladding is higher than that of the first cladding and is lower than those of the core and the common cladding. Further, at least a part of an inner cladding region, constituted by the first cladding and the second cladding, contains a photosensitive material having photosensitivity of changing a refractive index of a glass region containing the photosensitive material in response to irradiation of light with a specific wavelength.

Claim (Index 12):
A method for manufacturing a fiber Bragg grating, the method comprising:\n arranging a diffraction grating and a condensing lens, the condensing lens having a focal length of 300 to 1600 mm on a propagation path of ultraviolet light; installing the multicore optical fiber as set forth in  claim 1  so that a distance between a central axis of the multicore optical fiber and a light emission surface of the diffraction grating becomes 250 \u03bcm or less; irradiating the diffraction grating with the ultraviolet light via the condensing lens; and irradiating any one of the plurality of light guiding structures of the multicore optical fiber with a periodic interference fringe formed by the diffraction grating, to write a grating in the light guiding structure irradiated with the interference fringe.
