    Abstract: A system for disinfecting a medical device is provided. The system includes a light source that generates light having at least one wavelength between about 100 nm and about 500 nm. The system further includes at least one cylindrical optical diffuser disposed in optical communication with at least one interior channel of a medical device, the at least one cylindrical optical diffuser having an outer surface and an end optically coupled to the light source. The at least one cylindrical optical diffuser is configured to scatter guided light through the outer surface to form a light diffuser portion having a length that emits substantially uniform radiation over its length.

    Abstract: According to embodiments, an optical fiber may include a core portion comprising a radius rC, a centerline CL, a numerical aperture NA greater than or equal to 0.15 and less than or equal to 0.25, a graded relative refractive index profile having a maximum relative refractive index ΔCmax and an α value greater than or equal to 1 and less than or equal to 3. The core portion may include an up-dopant with a graded concentration from the radius rC to the centerline CL and an attenuation dopant with a constant concentration from the centerline CL of the core portion to the radius rC of the core portion. The optical fiber is multi-moded for wavelengths of light within a range from 800 nm to 1350 nm and an attenuation of the optical fiber wavelengths between 800 nm and 1000 nm is greater than or equal to 0.5 dB/m.

    Abstract: A fiber to waveguide coupler is provided that includes an optical fiber having a core and a cladding. The cladding includes an inner cladding and an outer cladding with a polymer. At least one of the core and inner cladding defines a substantially flat surface parallel with an axis of the optical fiber. The optical fiber defines a stripped portion substantially free of outer cladding configured to expose the at least one substantially flat surface of the core or inner cladding. A waveguide is configured to be evanescently coupled with the exposed at least one substantially flat surface of the core or inner cladding.

    Abstract: Embodiments of the disclosure relates to a light-diffusing element. The light diffusing element includes a glass core having a first refractive index. The light diffusing element also includes a cladding surrounding the glass core. The cladding includes an inner cladding surface and an outer cladding surface. The inner cladding surface and the outer cladding surface define a cladding thickness of from 5 μm to 30 μm. The cladding has a second refractive index that is less than the first refractive index of the glass core. The light diffusing element also includes a coating surrounding the cladding. The coating has an inner coating surface and an outer coating surface. The inner coating surface contacts the outer cladding surface. The outer coating surface defines an outermost surface of the light-diffusing element, and the coating includes first scattering centers.
