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.

Textured surfaces for display applications

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.

Optical transmission systems and methods using a QSM large-effective-area optical fiber

According to one embodiment, a system for transmitting differential optical signals can include an optical modulation device, a multi-core optical waveguide, and a balanced optical receiver. The optical modulation device can include at least one optical input port and multiple optical output ports. The optical modulation device can transform the optical input signal into multiple complimentary modulated optical signals that are transmitted from the multiple optical output ports. The multi-core optical waveguide can include multiple cores disposed within a cladding material. The multiple cores, the cladding material, or both can be configured to mitigate transmission of optical energy between the multiple cores. The balanced optical receiver can include multiple photodetectors. The balanced optical receiver can be communicatively coupled to the multiple cores of the multi-core optical waveguide. Each of the multiple photodetectors can transform at least one of the multiple complimentary modulated optical signals into an electrical signal.

Systems for differential optical signaling

A system for measuring the state of polarization (SOP) of an optical signal. The system includes a tunable local oscillator providing a local optical signal. A polarization transformer is operatively connected to the local oscillator and transforms the local optical signal to a selected one of a plurality of polarizations. A coupler combines an optical signal from the polarization transformer with an input optical signal from an optical system. A heterodyne detector is operatively connected to the coupler to detect the beat frequency of the signal from the coupler and provide an output signal that can be utilized to determine the state of polarization of an input optical signal.
