摘要： A light extraction film laminated to a glass substrate for organic light emitting diode (OLED) devices. The light extraction film includes a flexible substantially transparent film, a low index nanostructured layer applied to the film, and a high index planarizing backfill layer applied over the nanostructured layer. A glass substrate is laminated to the flexible substantially transparent film on a side opposite the nanostructured layer and including an ultra-low index region between the film and the glass substrate. The ultra-low index region is used to reduce optical losses occurring with the glass substrate.

摘要： A multifunctional optical film for enhancing light extraction includes a flexible substrate, a structured layer, a high index backfill layer, and an optional passivation layer. The structured layer effectively uses microreplicated diffractive or scattering nanostructures located near enough to the light generation region to enable extraction of an evanescent wave from an organic light emitting diode (OLED) device. The backfill layer has a material having an index of refraction different from the index of refraction of the structured layer. The backfill layer also provides a planarizing layer over the structured layer in order to conform the light extraction film to a layer of an OLED display device. The film may have additional layers added to or incorporated within it to an emissive surface in order to effect additional functionalities beyond improvement of light extraction efficiency.

摘要： A device and method for compensating for chromatic dispersion in an optical signal. The optical signal is coupled between an optical waveguide of a type having (i) a fundamental-mode waveguide and (ii) a higher-order mode waveguide surrounding the fundamental-mode waveguide, wherein different effective indexes of refraction are associated with the fundamental-mode and higher-order mode waveguides. The device comprises a transmissive, long-period optical grating disposed along a length of the optical waveguide and has a receiving end and a transmitting end. The grating is chirped between the ends along a light conducting axis of the optical waveguide such that different wavelengths of the optical signal are coupled to the fundamental-mode and higher order mode waveguides at different points along the length of the grating so that chromatic dispersion is corrected at the transmitting end.

摘要： A system and method for fabricating structures in an optical substrate. An optical element produces first and second write beams that intersect at a first intersection location at the optical substrate. The first intersection location includes a fringe pattern produced by the first and second write beams. The optical element also produces first and second reference beams that intersect and are recombined at a second intersection location in substantially the same plane as the first intersection location. A controller then controls relative positioning between the optical substrate and the fringe pattern based on a signal derived from the recombined first and second reference beams.

摘要： Long-period gratings are written more quickly and at higher intensities by amplitude masks having shadow-forming patterns that scatter, redirect, or otherwise divert shadow portions of radiation used for writing the gratings instead of blocking the shadow portions by absorption or reflection. The shadow-forming masks can be formed along transparent base optics by arrays of diffusers, diffractors, or refractors that relatively divert different portions of the radiation.
