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 1):
A multicore optical fiber which is mainly comprised of silica glass and comprises: a plurality of light guiding structures each extending in a central axis direction; and a single common cladding surrounding the plurality of light guiding structures, wherein\n each of the plurality of light guiding structures includes: a core extending in the central axis direction; a first cladding provided on an outer periphery of the core, the first cladding having a refractive index lower than a refractive index of the core; and a second cladding provided on an outer periphery of the first cladding, the second cladding having a refractive index higher than the refractive index of the first cladding, lower than the refractive index of the core, and lower than an refractive index of the common cladding, and 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 doped with the photosensitive material in response to irradiation of light having a specific wavelength.
