Temporal self-imaging effect in single-mode fibers
TL;DR: In this paper, the simulation of signal propagation in a single-mode fiber is considered by using the analogous Fresnel diffraction experiment, where the transfer of information in fibers with a large dispersion of the first order is accomplished by a temporal analog of the self-imaging effect.
Patent
Liquid crystal display system with internally reflecting waveguide for backlighting and non-Lambertian diffusing
TL;DR: In this paper, a system for providing an LCD with a collimated backlight and a non-Lambertian diffuser is described, where the light from the reflector is directly incident upon the incident end.
Patent
High modulation rate optical plasmon waveguide modulator
TL;DR: In this article, a high-speed light modulator employing surface plasmon wave coupling is proposed, where a metal dielectric interface is positioned adjacent to and externally of a waveguide carrying totally internally reflected light waves.
Patent
Authentication system and method
TL;DR: In this paper, an authentication system using a correlator that correlates an input with a reference wherein at least one of the input and reference comprises a phase volume mask having structures, preferably points, that are each less than about six microns in size and can have an aspect ratio (AR) greater than 1:1 so as to produce a phase encoded random pattern having millions of combinations in a mask that is as small as one square millimeter.
Patent
Backlight apparatus for illuminating a display with controlled light output characteristics
TL;DR: In this paper, a beam bending and viewing film including a surface diffuser and a second side including a plurality of substantially parallel optical elements, each of which includes a refractive surface and a total internal reflection surface, is described.
