Reflective film combinations with output confinement in both polar and azimuthal directions and related constructions
A reflective film includes microlayers arranged into optical repeat units to reflect light in an extended wavelength band, with thinner and thicker ones of the optical repeat units being disposed generally towards a thin side and thick side, respectively, of the film. The microlayers are tailored to provide the film with a reflectivity, for p-polarized light incident in a first plane, that decreases by at least half from an initial value at normal incidence to a value R1 at an incidence angle θoblique. The film has a reflectivity for p-polarized light incident in a second plane of R2 at the angle θoblique, where R2>R1. A polarizer is combined with the reflective film, the combination defining an oblique transmission lobe, and the thick and thin sides of the reflective film are oriented relative to the polarizer to reduce an azimuthal width Δφ of the transmission lobe. |

Microreplicated film for attachment to autostereoscopic display components
Microreplicated light redirecting films suitable for use in autostereoscopic displays and backlights are made to incorporate at least one nanovoided layer whose interface with another layer forms an embedded structured surface of the light redirecting film. The nanovoided layer includes a polymer binder and optional nanoparticles, and may have a refractive index less than 1.35 or 1.3. The light redirecting films may be adapted for attachment to one or more other components of an autostereoscopic display, such as a display panel and/or a light guide of a backlight. |

Chip-based frequency comb generator with microwave repetition rate
A frequency comb generator fabricated on a chip with elimination of a disadvantageous reflow process, includes an ultra-high Q disk resonator having a waveguide that is a part of a wedge structure fabricated from a silicon dioxide layer of the chip. The disk resonator allows generation of a frequency comb with a mode spacing as low as 2.6 GHz and up to 220 GHz. A surface-loss-limited behavior of the disk resonator decouples a strong dependence of pumping threshold on repetition rate. |
