摘要： A stereoscopic optical system includes two parallel optical systems that each include, in order from an object side to an image side, a front unit having a negative refractive power, an intermediate unit having two reflective surfaces, and a rear unit. A distance between optical axes of rear units is smaller than that between optical axes of front units in the two optical systems due to bending of an optical path by the two reflective surfaces. At least one of the intermediate unit and the rear unit has a positive refractive power. The front unit includes, in order from the object side to the image side, a first subunit consisting of one or more negative lenses disposed on the object side of a positive lens closest to an object in the front unit, and a second subunit having a positive power. A predetermined condition is satisfied.

摘要： A privacy film may have a light-blocking layer that is interposed between first and second transparent substrates. The light-blocking layer may have a plurality of opaque portions and a plurality of transparent portions. The opaque portions may be shaped to ensure light from the display is directed only to the primary viewer of the display. Each opaque portion of the light-blocking layer may extend along a respective longitudinal axis between the first and second transparent substrates. Privacy films used to cover curved displays may have opaque portions that extend along longitudinal axes that have different angles relative to the transparent substrates. Opaque portions in the edge of the privacy film may have longitudinal axes that are at non-perpendicular angles with respect to the transparent substrates. A privacy film for a curved display may also include a light-redirecting layer such as a prism layer or a liquid crystal layer.

摘要： An active metasurface that provides low-loss and high-bandwidth modulation control of light includes a number of cells arranged on a substrate. A controller dynamically alters a voltage differential supplied to the electrodes of each of the cells is adapted to alter refractive index of each of the high-index dielectric blocks in order to controllably steer light exiting the cell.

摘要： Disclosed is a method for cutting dielectric or semiconducting material with a laser. The method includes the following steps: emission of a laser beam including at least one burst of N femtoseconds laser pulses; spatial separation of the laser beam into a first split beam having a first energy, and respectively, a second split beam having a second energy; spatial concentration of energy of the first split beam in a first zone of the material, respectively, of the second split beam in a second zone of the material, the first zone and the second zone being separate and staggered by a distance dx; and adjustment of the distance between the first zone and the second zone in such a way as to initiate a straight micro-fracture oriented between the first zone and the second zone.

摘要： A plasmonic device incorporating a special hyperbolic metamaterial (HMM) metamaterial is used for plasmonic lithography, including ultraviolet (UV) lithography. It may be a Type II HMM (ϵ∥ 0) whose tangential component of the permittivity ϵ∥ is close to zero. Due to the high anisotropy of the Type II epsilon near zero (ENZ) HMM, only one plasmonic mode can propagate horizontally with low loss in a waveguide system with ENZ HMM as its core. In certain aspects, a Type II ENZ HMM comprises alternating layers of aluminum/aluminum oxide films and the associated unusual mode of light transmission is used to expose a photosensitive layer in a specially designed lithography system. Methods for making patterns of nanofeatures via such plasmonic lithography are also provided, including as a plasmonic roller device.
