Abstract: A substrate with a textured surface is disclosed. The substrate may be, for example, a light emitter comprising a light guide, for example a backlight element for use in a display device, wherein a surface of the light guide, for example a glass substrate, is configured to have a textured surface with a predetermined RMS roughness and a predetermined correlation length of the texture. A plurality of light scatter suppressing features can be provided on the textured surface. Textured surfaces disclosed herein may be effective to reduce electrostatic charging of the substrate surface. Methods of producing the textured surface are also disclosed.

Abstract: A light diffusing component and a method of making is disclosed. The light diffusing component may include a substrate sheet and at least one scattering layer. The substrate sheet may have a back side and an edge. The edge may be configured to receive a light source. The at least one scattering layer may have a plurality of light scattering centers etched into at least a portion of the back side of the glass sheet. The scattering centers may have an increased density as the distance from the edge increases. The scattering centers may have a diameter of less than about 30 microns, a maximum depth of about 10 micron or less, and a roughness between about 0.5 nm to about 100 nm, for example.

Abstract: Optical transmission systems and methods are disclosed that utilize a QSM optical fiber with a large effective area and that supports only two modes, namely the fundamental mode and one higher-order mode. The optical transmission system includes a transmitter and a receiver optically coupled by an optical fiber link that includes at least one section of the QSM optical fiber. Transmission over optical fiber link gives rise to MPI, which is mitigated using a digital signal processor. The QSM optical fiber is designed to have an amount of DMA that allows for the digital signal processor to have reduced complexity as reflected by a reduced number of filter taps as compared to if the DMA were zero.
