Abstract: A photonic crystal fiber according to the present invention has a plurality of holes arranged in the optical fiber along a longitudinal direction, in which the holes are arranged such that, in a cross section, a hole ratio which is an area of the holes per unit area is larger in a central side than in an outer side in a portion corresponding to a cladding and that a wide core area can be obtained while the number of modes that can be propagated is limited to several. Moreover, in a high-power optical transmission system according to the present invention, the amount of axis misalignment between the central axis of a laser oscillator and the central axis of the photonic crystal fiber is less than or equal to a certain amount.

Abstract: A supercontinuum optical pulse source provides a combined supercontinuum. The supercontinuum optical pulse source comprises one or more seed pulse sources (13), and first and second optical amplifiers (7) arranged along first and second respective optical paths. The first and second optical amplifiers are configured to amplify one or more optical signals generated by said one or more seed pulse sources. The supercontinuum optical pulse source further comprises a first microstructured light-guiding member (9) arranged along the first optical path and configured to generate supercontinuum light responsive to an optical signal propagating along said first optical path, and a second microstructured light-guiding member (9) arranged along the second optical path and configured to generate supercontinuum light responsive to an optical signal propagating along said second optical path. The supercontinuum optical pulse source further comprises a supercontinuum-combining member (5) to combine supercontinuum generated in at least the first and second microstructured light-guiding members to form a combined supercontinuum. The supercontinuum-combining member comprises an output fibre, wherein the output fibre comprises a silica-based multimode optical fibre supporting a plurality of spatial modes at one or more wavelengths of the combined supercontinuum.

Abstract: An illuming device for use in medically illuminating tissue of interest within a patient generally includes a light diffusing optical fiber and an at least partially optically opaque sheath that is mounted over the fiber for selective, sliding movement along the length thereof. By sliding the sheath relative to the optical fiber after it has been inserted into a patient to illuminate a particular area of tissue, the length, size, and/or shape of the light that is exposed to the tissue can be selectively controlled. Such in situ variation of the properties of the exposed light permit use of a single instrument and a single procedure regardless of variation in the size and shape of the diseased tissue being medically treated.

Abstract: The fibre comprises a core (2) of index N and diameter 10 µm or more, surrounded by a ring (4) of index N+Δn and thickness ΔR, and a sheath (6) surrounding the ring and comprising, for example, air holes (8). According to the invention: Δn ≥ 10
-3 and ΔR = α/(Δn)
β [1] where: 5x10
-4 µm≤α≤5x10
-2 µm and 0.5≤β≤1.5. Numbers α and β depend on the wavelength λ of the light guided by the fibre, the number of missing holes in same, the diameter
d of the holes, the spacing Λ between same and N. The designing of the fibre comprises the steps of: selecting λ, the number of missing holes, d/Λ, the doping level of the core, Λ and Δn; and determining ΔR by the aforementioned relation [1] such as to obtain a flattened fundamental mode.
