System And Method For Measurement Of The State Of Polarization Over Wavelength

View page
US Patent:
20020140943, Oct 3, 2002
Filed:
Feb 16, 2001
Appl. No.:
09/785641
Inventors:
Dipakbin Chowdhury - Corning NY, US
Ioannis Roudas - North Brunswick NJ, US
Richard Vodhanel - Red Bank NJ, US
International Classification:
G01B009/02
US Classification:
356/484000
Abstract:
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.

Texture Gradient For Uniform Light Output From A Transparent Backlight

US Patent:
20180095330, Apr 5, 2018
Filed:
Apr 5, 2016
Appl. No.:
15/564986
Inventors:
- CORNING NY, US
Ioannis Georgios Roudas - Bozeman MT, US
Adama Tandia - Nelson PA, US
Aramais Robert Zakharian - Painted Post NY, US
International Classification:
G02F 1/1335
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.

Textured Surfaces For Display Applications

US Patent:
20180059309, Mar 1, 2018
Filed:
Oct 24, 2017
Appl. No.:
15/792167
Inventors:
- Corning NY, US
Vasudha Ravichandran - Painted Post NY, US
Ioannis Georgios Roudas - Bozeman MT, US
Christine Coulter Wolcott - Horseheads NY, US
International Classification:
F21V 8/00
C03C 15/00
G02B 5/02
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.

US Patent:
20140205300, Jul 24, 2014
Filed:
May 22, 2013
Appl. No.:
13/899842
Inventors:
- Corning NY, US
Ioannis Roudas - Big Flats NY, US
Assignee:
Corning Incorporated - Corning NY
International Classification:
H04B 10/2575
H04L 27/02
US Classification:
398116
Abstract:
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.
