摘要： An optical fiber that is relatively insensitive to bend loss comprises a core region and a cladding region configured to support and guide the propagation of light in a fundamental transverse mode, the cladding region including (i) an outer cladding region having a refractive index less than that of the core region, (ii) an annular cladding pedestal region having a refractive index higher than that of the outer cladding region and comparable to that of the core region, and (iii) an annular cladding inner trench region disposed between the core region and the pedestal region, the inner trench region having a refractive index less than that of the outer cladding region. In one embodiment, the fiber also includes a (iv) an annular cladding outer trench region disposed between the pedestal region and the outer cladding region, the outer trench region having a refractive index less than that of the outer cladding region. In addition, to suppress HOMs the pedestal region is configured to resonantly couple at least one other transverse mode of the core region to at least one transverse mode of the pedestal region. Such fiber is advantageously used as access fiber, but may have other applications, such as sensor fiber.

摘要： PROBLEM TO BE SOLVED: To provide an optical fiber which is manufactured simply and economically and in which stimulated Brillouin scattering is suppressed. SOLUTION: The optical fiber includes a core part 10, having a refractive index larger than that of a clad part 11, and the mode-field radius of light is made larger than the radius of the core part 10; the overlapped integration of the electric field distribution of light and the acoustic wave basic mode distribution is reduced; and thus the stimulated Brillouin scattering is suppressed.

摘要： PROBLEM TO BE SOLVED: To solve the problem that, in a conventional air clad optical fiber, as a core supporting body is inserted between a core and a protective tube while contacting the core to support the core in the air, light is leaked at a contact point and optical fiber transmission property is degraded, and as both ends of the optical fiber are open to the outside, dirt, dust, abrading agent, water, and the like enter a core part which is subjected to air clad, the transmission property and reliability are degraded. SOLUTION: Provided are an air clad optical fiber in which a shape of the core is made a cone shape so that a core size becomes large at the both ends of the optical fiber, the core is made to contact the protective tube only at the both ends and made to be integrated with the protective tube, thereby the core is maintained in the air without any supporting body, and the both ends are closed so that the core part which is subjected to air clad does not directly contact the outside. Its manufacturing method is also provided. COPYRIGHT: (C)2010,JPO&INPIT
