摘要： A multicore optical fiber includes two or more cores, a common interior cladding surrounding the two or more cores, and a common exterior cladding surrounding the common interior cladding. The common exterior cladding has a lower relative refractive index than the common interior cladding and reduces tunneling losses from the cores. The reduced tunneling loss allows placement of cores closer to the edge of the fiber, thus providing multicore optical fibers having higher core count for a given fiber diameter. Separation between cores is controlled to minimize crosstalk.

摘要： Systems and methods utilizing two Airy beams to process a non-rounded edge of a glass substrate or to cleave a glass substrate are disclosed. The method includes generating first and second Airy beams and causing them to cross at a crossing to define a curved intensity profile in the vicinity of the crossing point where the first and second Airy beams have respective local radii of curvature RA and RB. The method also includes scanning the curved intensity profile either along the non-rounded outer edge or through the glass along a scan path to form on the glass substrate a rounded outer edge having a radius of curvature RE that is smaller than the first and second local radii of curvature RA and RB. The radius of curvature RE can be adjusted by changing a beam angle between the first and second Airy beams.
