Abstract: Assemblies, optical connectors, and methods for bonding optical elements to a substrate using a laser beam are disclosed. In one embodiment, a method of bonding an optical element to a substrate includes disposing a film layer on a surface of the substrate, disposing the optical element on a surface of the film layer, and directing a laser beam into the optical element. The method further includes melting, using the diameter laser beam, a material of the substrate to create a bond area between the optical element and the surface of the substrate. The film layer is capable of absorbing a wavelength of the laser beam to melt the material of the substrate at the bond area. The bond area includes laser-melted material of the substrate that bonds the optical element to the substrate.

Abstract: Layered glass structures and fabrication methods are described. The methods include depositing soot on a dense glass substrate to form a composite structure and sintering the composite structure to form a layered glass structure. The dense glass substrate may be derived from an optical fiber preform that has been modified to include a planar surface. The composite structure may include one or more soot layers. The layered glass structure may be formed by combining multiple composite structures to form a stack, followed by sintering and fusing the stack. The layered glass structure may further be heated to softening and drawn to control linear dimensions. The layered glass structure or drawn layered glass structure may be configured as a planar waveguide.

Abstract: A multicore fiber is provided. The multicore fiber includes a plurality of cores spaced apart from one another, and a cladding surrounding the plurality of cores and defining a substantially rectangular or cross-sectional shape having four corners. Each corner has a radius of curvature of less than 1000 microns. The multicore fiber may be drawn from a preform in a circular draw furnace in which a ratio of a maximum cross-sectional dimension of the preform to an inside diameter of the preform to an inside diameter of the draw furnace is greater than 0.60. The multicore fiber may have maxima reference surface.

Abstract: Laser waveguides, methods and systems for forming a laser waveguide are provided. The waveguide includes an inner cladding layer surrounding a central axis and a glass core surrounding and located outside of the inner cladding layer. The glass core includes a laser-active material. The waveguide includes an outer cladding layer surrounding and located outside of the glass core. The inner cladding, outer cladding and/or core may surround a hollow central channel or bore and may be annular in shape.

Abstract: Multicore optical fibers that include between two and ten multimode cores surrounded by a cladding matrix and symmetrically arranged about a fiber axis are disclosed, with no core running along the fiber axis. The cores include a trench to stabilize delays of the higher order modes, which tend to propagate faster than do the central modes due to the amount of power at the core-clad interface. The trench also suppresses crosstalk and power leakage. The core configuration promotes efficient optical alignment and optical coupling with other multicore optical fibers or light sources, such as VSCEL and silicon-photonics light sources.
