Abstract: A volume holographic imaging system enables the projection of a two-dimensional (2D) slice of a four-dimensional (4D) object. The 4D source object is illuminated to emit or scatter an optical field. A holographic element having one or more recorded holograms receives and diffracts the optical field into a diffracted plane beam. A phase mask is encoded in one or more multiplexed holographic gratings of the holographic element using a spatial filter. A collector lens focuses the diffracted plane beam to a 2D slice of the 4D probing source object. The focused 2D slice is projected onto a 2D imaging plane. The holographic element may have multiple multiplexed holograms that are arranged to diffract light from a corresponding slice of the 4D probing source object to a non-overlapping region of the detector.

Abstract: A switching system is disclosed for an optical signal. The switching system includes a first optical waveguide coupled to a first electrode, a second electrode, and a second optical waveguide. The second optical waveguide is coupled to a movable electrode. The movable electrode is supported by a support structure and is positioned with respect to the first and second electrodes so that the position of the movable electrode may be selectively placed in either a first closed state or a second open state defined by the first and second electrodes under application of a voltage with respect to one of the first and second electrodes. The first closed state provides that the first and second optical waveguides are sufficiently close to each other to provide optical coupling therebetween while the second open state provides that the first and second optical communication channels are not sufficiently close to each other to provide optical coupling therebetween, or provide some different amount of optical coupling than in the first closed state.

Abstract: A lithography system includes a source of radiation energy and a zone plate array to focus the radiation energy to create an array of images in order to produce a permanent pattern on a substrate. A phase-shift mask is optically located between the source of radiation energy and the zone plate array. The modulated wavefront produced by the phase-shift mask alters the field diffracted by the zone plate array, and the center lobe of the point-spread function narrows as a result.

Abstract: A micro-opto-electro-mechanical systems (MOEMS) modulator based on the phenomenon of frustrated total internal reflection (FTIR). The modulator effects amplitude and phase modulation at the boundary of a waveguide. Wavelength-specific switching is achieved by spatially separating the wavelength channels by dispersing a broadband input signal into its wavelength components through a grating. In exemplary embodiments, an array of micro-fabricated actuators is used to switch or modulate wavelengths individually. Applications include wavelength and space-resolved phase and amplitude modulation of optical beams, and re-configurable add/drop switching of dense wavelength-division multiplexed (DWDM) optical communication signals.

Abstract: The invention is embodied in a method of recording successive holograms in a recording medium, using at least a fan of M waves along at least a first axis with a separation angle between adjacent waves and directing the fan of M waves as a reference beam along a reference beam path onto the recording medium, successively modulating a wave with a succession of images to produce a succession of signal beams along a signal beam path lying at a propagation angle relative to the reference beam path so that the signal and reference beams intersect at a beam intersection lying within the medium, the beam intersection having a size corresponding to beam areas of the reference and signal beams, producing a succession of relative displacements in a direction parallel to the first axis between the recording medium and the beam intersection of the signal and reference beam paths in synchronism with the succession of signal beams, each of the displacements being less than the size of the intersection whereby to record successive holograms partially overlapped along a direction of the displacements.
