Abstract: Disclosed herein are methods of bonding a multi-layer film to a substrate and resulting structures thereof. A method of laser bonding a multi-layer film to a substrate can include forming a film over a first surface of a first substrate that is transmissive to light at a first wavelength. The film may include a reflective layer that is reflective to light at the first wavelength and a refractive layer that is refractive to light at the first wavelength. The method may include irradiating a region of the film using laser radiation passing through the first substrate. A wavelength profile of the laser radiation can have a peak at about the first wavelength. The first wavelength can be between about 300 nm and about 5000 nm.

Abstract: A curing apparatus for curing a coating composition disposed on an optical fiber, the curing apparatus including a first light source and a second light source such that the second light source is spaced from the first light with a gap. The curing apparatus further including a first reflector and a second reflector such that the second reflector is spaced from the first reflector with the gap. Furthermore, a spacer is disposed within the gap, the spacer being formed of a material configured to reflect at least about 90% of light emitted from the first light source and from the second light source, and incident on the spacer, to an optical fiber such that the reflected light has sufficient intensity to cure a coating on the optical fiber.

Abstract: An illumination system generating light having at least one wavelength within 200 nm a plurality of nano-sized structures (e.g., voids). The optical fiber coupled to the light source. The light diffusing optical fiber has a core and a cladding. The plurality of nano-sized structures is situated either within said core or at a core-cladding boundary. The optical fiber also includes an outer surface. The optical fiber is configured to scatter guided light via the nano-sized structures away from the core and through the outer surface, to form a light-source fiber portion having a length that emits substantially uniform radiation over its length, said fiber having a scattering-induced attenuation greater than 50 dB/km for the wavelength(s) within 200 nm to 2000 nm range.

Abstract: A light diffusing optical fiber includes a glass core, a cladding, a phosphor layer surrounding the cladding, and a plurality of scattering structures positioned within the glass core, the cladding, or both. The phosphor layer includes two or more phosphors and is configured to convert guided light diffusing through the phosphor layer into emission light such that the color of the emission light has a chromaticity within a u′-v′ chromaticity region on a CIE 1976 chromaticity space defined by: a first u′-v′ boundary line and a second u′-v′ boundary line that extend parallel to a planckian locus at a distance of ±0.02 Duv from the planckian locus, a third u′-v′ boundary line that extends along an isothermal line for a correlated color temperature of about 2000 K, and a fourth u′-v′ boundary line that extends along an isothermal line for a correlated color temperature of about 10000 K.

Abstract: An optical fiber includes a core portion having a radius rC and a graded refractive index profile ΔC having an alpha value greater than or equal to 1 and less than or equal to 8. The core portion includes a silica-based glass and a down-dopant, where a concentration of the down-dopant is graded such that the concentration of the down-dopant decreases from the radius rC towards the center of the core portion. The optical fiber comprises a cladding portion surrounding the core portion and having a relative refractive index ΔOC that is less than a maximum refractive index ΔCmax of the core portion.

Abstract: An illumination system (100) includes a light diffusing optical fiber (110) and a light output device (140) having a light source (142). The light diffusing optical fiber (110) includes a first end (112), a second end (114), a core (120), a cladding (122) surrounding the core (102), an outer surface (128), and a plurality of nano-sized structures (125) configured to scatter guided light through the outer surface (128). The light diffusing optical fiber (110) has a numerical aperture NALDF. The light output device (140) has an effective numerical aperture NA0, which is less than the numerical aperture NALDF of the light diffusing optical fiber (110). Further, the light output device (140) is optically coupled to an end face (116) of the first end (112) of the light diffusing optical fiber (110) such that light output by the light source of the light output device irradiates the end face (116) at an incident angle θi that is non-orthogonal to the end face (116) and is within approximately 5° of sin−1 NALDF−sin−1 NA0.

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.
