The present disclosure relates to methods of assembling a lensed optical fiber array by printing in situ a lens onto each optical fiber of an optical fiber array with an ultrafast laser system where the lens can be shaped to the optical fiber end face to reduce pitch mismatch. In some embodiments, optical fiber(s) of the optical fiber array can be cleaved, and the lens can be shaped to the optical fiber end face to reduce pitch mismatch.

A fiber coupling assembly for interfacing solid core and a hollow core optical fibers includes first and second fiber optic ferrules each having a bore between proximal and distal end faces thereof. At least one ferrule end face is non-perpendicular to longitudinal axes of the ferrules. A bore of one ferrule contains a hollow core optical fiber, and a bore of the other optic ferrule contains a solid core optical fiber with a mode field diameter (MFD) transition region, to bridge a MFD mismatch between the fibers. An air gap may be provided between at least portions of ferrules at an inter-ferrule region. A fiber optic ferrule includes a bore that is non-parallel with a longitudinal axis of the ferrule, and at least one end face that is non-perpendicular to the longitudinal axis, with an optical fiber in the bore optionally including a MFD transition region.

The present disclosure relates to a process by which an optical fiber array is cleaved with a laser-cleaving apparatus. The coating material is stripped or removed from a section of an optical fiber array; a coated or ribbonized section of the optical fiber array is secured in a holder; the holder is aligned inside the laser-cleaving apparatus; the laser cleaves the stripped ends of the fibers in the optical fiber array; the laser-cleaved ends of the optical fibers are then mechanically separated to remove the free ends from the optical fibers in the optical fiber array, leaving a cleaved array of optical fibers. The cleaving process enables the optical fiber array to be cleaved at flexible locations along an optical fiber ribbon or optical fiber cable with no swelling, minimal cleave angle variation across the cores of the optical fibers, a controlled surface roughness of the optical fiber end-faces, and high process yield.

The present disclosure relates to a process by which an optical fiber array or a single optical fiber is cleaved with a laser-cleaving apparatus. The coating material is stripped or removed from a section of an optical fiber array or single optical fiber; a coated or ribbonized section of the optical fiber array or the single optical fiber is secured in a holder; the holder is aligned inside the laser-cleaving apparatus; the laser cleaves the stripped ends of the fibers in the optical fiber array or the single optical fiber; the laser-cleaved ends of the optical fiber(s) are then mechanically separated to remove the free ends from the optical fibers in the optical fiber array or the single optical fiber, leaving a cleaved array of optical fibers or a single cleaved optical fiber. The cleaving process enables the optical fiber array or single optical fiber to be cleaved at flexible locations along an optical fiber ribbon, optical fiber, or optical fiber apparatus (e.g., cleaving can be performed close to a ferrule end face) with no swelling, minimal cleave angle variation across the cores of the optical fibers, a controlled surface roughness of the optical fiber end faces, and high process yield.

Protected splice joints may be provided between a multi-fiber ferrule and a boot of a connector, with at least a portion of a split jacket section of a fiber optic cable arranged within the boot. The jacket may have a split length of less than 25 mm and/or an entirety of the split jacket is within the boot. If provided, heat shrink tubing covering the split jacket may have a reduced length and/or may be confined within the boot.
