    Abstract: Single mode optical fibers with a chlorine doped core and a cladding having a fluorine doped trench region are disclosed. The optical fiber includes a chlorine doped silica core having a core alpha α≥10, a core radius r1 and maximum refractive index delta Δ1max % and a Cl concentration≥0.9 wt %. The optical fiber also has a cladding surrounding the core, the cladding having an inner and an outer cladding. The inner cladding has first and second cladding regions. The optical fiber has mode field diameter at 1310 nm of larger than 9 microns, a cable cutoff wavelength of ≤1260 nm, a zero dispersion wavelength λ0, where 1300 nm≤λ0≤1324 nm, and bend loss at 1550 nm for a 20 mm mandrel of less than 0.5 dB/turn.

    Abstract: An optical assembly includes a transparent substrate having a first major surface and a second major surface. The transparent substrate includes one or more damage layers disposed between a first non-damage layer and a second non-damage layer. Elongated laser-induced damage tracks are disposed within the damaged layer(s) to form at least one area pattern so that light directed toward the transparent substrate at an angle that exceeds a predetermined viewing angle (θ) is scattered by the plurality of laser-induced damage tracks. Alternatively, if light is directed toward the transparent substrate at an angle that is less than the predetermined viewing angle (θ), it is transmitted by the transparent substrate.

    Abstract: Methods of manufacturing multi-mode optical fiber, and multi-mode optical fiber produced thereby, are disclosed. According to embodiments, a method for forming an optical fiber may include heating a multi-mode optical fiber preform and applying a draw tension to a root of the multi-mode optical fiber preform on a long axis of the multi-mode optical fiber preform thereby drawing a multi-mode optical fiber from the root of the multi-mode optical fiber preform. The draw tension may be modulated while the multi-mode optical fiber is drawn from the root of the multi-mode optical fiber preform. Modulating the draw tension introduces stress perturbations in the multi-mode optical fiber and corresponding refractive index perturbations in a core of the multi-mode optical fiber.
