Abstract: The magnifying apparatus is based on two dimensional arrays of micro magnifying modules (MMMs) positioned along a plane perpendicular to the axis of the magnifying apparatus. In addition, the structure may include a two dimensional array of micro beam multipliers (MBMs) to improve the quality of the magnified image. The micro beam multipliers are positioned along a plane parallel to the array of micro magnifying modules. The structure also may include a two dimensional array of ray angle adjusters (RAAs) to extend the view angle. The ray angle adjusters are positioned along a plane parallel to the array of micro magnifying modules. The array of micro magnifying modules, with or without the micro beam multipliers and/or ray angle adjusters, may be constructed as a thin plate with a thickness of a few millimeters, through which the object is viewed.

Abstract: Described are new magnifying apparatus based on two dimensional arrays of micro magnifying modules (MMMs) positioned along a plane perpendicular to the axis of the MMMs. In addition, the structure may include a two dimensional array of micro beam multipliers (MBMs) to improve the quality of the image. The micro beam multipliers are positioned along a plane parallel to the array of micro magnifying modules. The array of micro magnifying modules, with or without the micro beam multipliers, may be constructed as a thin plate with a thickness of a few millimeters, through which the object is viewed. An object at a distance appears in the magnifying apparatus as a magnified image and the magnifying apparatus can be used for viewing an object at a distance in a way similar to the use of a conventional magnifier for viewing an object in a short distance.

Abstract: Various configurations of a virtually imaged phased array (VIPA) generator in combination with a mirror to compensate for chromatic dispersion. A VIPA generator produces a light traveling from the VIPA generator. In some embodiments, a variable curvature mirror is positioned to reflect the light back to the VIPA generator. A rotation axis around which the mirror is rotated and a translation path for the rotation axis are provided, to change the curvature of the mirror where the output light is reflected. In other embodiments, a plurality of mirrors have different surface curvatures. A holder has a rotation axis and holds the plurality of mirrors equidistantly from the rotation axis. The holder is rotatable around the rotation axis to bring a different, respective mirror in position to reflect light produced by a VIPA generator back to the VIPA generator. In other embodiments, a rotating mirror is rotatable about a rotation axis to reflect light produced by a VIPA generator to a respective fixed mirror.

Abstract: An optical wavelength division multiplexed system uses wavelength splitters to split channels included in input light into different paths within the system. Odd-numbered channels are split into one path, and even-numbered channels are split into another path, providing increased isolation between channels. Using filters, the system then drops one or more of the isolated, split channels into paths referred to as dropped paths and allows the remaining channels to continue through the filters into output paths. The dropped paths are then combined into one, common dropped path, and the output paths are also combined into one, common output path.

Abstract: An optical apparatus for producing chromatic dispersion. The apparatus includes a virtually imaged phased array (VIPA) generator, a mirror and a lens. The VIPA generator receives an input light at a respective wavelength and produces a corresponding collimated output light traveling from the VIPA generator in a direction determined by the wavelength of the input light, the output light thereby being spatially distinguishable from an output light produced for an input light at a different wavelength. The mirror has a cone shape, or a modified cone shape. The lens focuses the output light traveling from the VIPA generator onto the mirror so that the mirror reflects the output light. The reflected light is directed by the lens back to the VIPA generator. In this manner, the apparatus provides chromatic dispersion to the input light.

Abstract: Transmitters for generating inversely dispersed optical signals to counter chromatic dispersion in optical fibers carrying the optical signals are presented. The transmitters have optical pulse generators which generate in parallel inversely dispersed optical pulses which are combined for output into an optical fiber.
