摘要： To provide an optical probe for OCT and a method of manufacturing the optical probe that can reduce reflected light generated at a boundary portion between an optical fiber and a lensed fiber. An optical probe for OCT includes an optical fiber that transmits irradiation light and back-scattered light and a lensed fiber that is fusion spliced to an end face of the optical fiber, that emits irradiation light toward the inside of a living body while collimating the irradiation light, and that collects and guides back-scattered light to the end face of the optical fiber. A refractive index adjusting material is added to the lensed fiber, and the refractive index adjusting material is diffused in an end part of the optical fiber.

摘要： A few-mode optical fiber comprises a core surrounded by a cladding, having a step index profile that is structured to support propagation of a plurality of desired signal-carrying modes, while suppressing undesired modes. The core and cladding are configured such that the undesired modes have respective effective indices that are close to, or less than, the cladding index such that the undesired modes are leaky modes. The index spacing between the desired mode having the lowest effective index and the leaky mode with the highest effective index is sufficiently large so as to substantially prevent coupling therebetween.

摘要： Optical fibers Fp, Fn, included in a light transmission path, are two-mode optical fibers for propagating an LP01 mode component and an LP11 mode component contained in signal light, and a gradient dΔτ/dλ of a mode dispersion Δτ with respect to a wavelength λ in a wavelength band of 1530 nm to 1625 nm is |0.5| ps/km/nm or less. Symbols of mode dispersions Δτ of the optical fibers Fp, Fn are opposite to each other. The light transmission path can satisfactorily compensate the mode dispersion in a wide wavelength band.
