    摘要: A multicore optical fibre includes a microstructured cladding material formed from a plurality of cladding elements arranged in an array and each cladding element comprising at least two different materials each having different refractive indices, and a plurality of core elements formed within interstitial regions between adjacent cladding elements. A fibre so formed may have a large number of cores per unit cross-sectional area as compared with prior art fibres, and thus allows the fibre to have relatively short distances between adjacent cores for a given required inter-core isolation. A fibre so formed has utility in many areas requiring high core density, such as inter-chip optical communication, or optical communication between circuit boards.

    摘要: Connectorized nano-engineered optical fibers and method for forming them are disclosed. The methods include heating a mid-span bare fiber portion of the nano-engineered fiber to collapse the airlines therein so as to form an airline-free portion. The fiber is then inserted into a ferrule channel so that the fiber end protrudes beyond the ferrule end face, but with the airline-free portion positioned at the ferrule end face. The fiber is then cleaved at or near the ferrule end face in the airline-free portion, and the new fiber end face polished to create a solid fiber end face that coincides with the ferrule end face. The methods result in at most only minimal changes to the mode field diameter (MFD) and/or to the outer cladding diameter, which is essential in forming a connectorized nano-engineered fiber that can connect to like-size nano-engineered or non-nano-engineered fibers.

    摘要: Systems and methods of collapsing the air lines in the air line-containing region of a nanostructure optical fiber are disclosed. One method includes initiating irradiation of a portion of the nanostructure optical fiber from essentially opposite directions with at least first and second laser beams having substantially equal power and essentially the same mid-infrared wavelength. The method includes continuing the irradiation for an irradiation time t1 so as to bring the optical fiber portion to a softening temperature TS at which the air lines in the optical fiber portion collapse into the adjacent cladding. Exemplary optical systems for carrying out the air- line-collapsing methods of the present invention are also disclosed.
