    Abstract: An optical cross-connect connecting a series of optical input ports to a series of optical output ports includes at least a first group of input/output port arrays, each including a series of optical input/output ports disposed horizontally and configured to project or receive optical signals. A plurality of steering elements selectively steer optical signals along switching trajectories between the input and output ports. An angle-to-offset conversion unit converts optical signals propagating at the horizontal intra-array angles to corresponding spatial offset signals in the horizontal dimension. An optical interconnect includes a series of input/output regions, each being specific to a corresponding input/output port array and the input/output regions being divided vertically into elongated switching rows. Each input/output region receives spatial offset signals from the angle-to-offset conversion unit and optically interconnects each spatial offset signal from a first input/output region to a second input/output region.

    Abstract: Described herein is a wavelength selective switch (WSS) type optical switching device (1) configured for switching input optical beams from input optical fiber ports (3, 5 and 7) to an output optical fiber port (9). Device (1) includes a wavelength dispersive grism element (13) for spatially dispersing the individual wavelength channels from an input optical beam in the direction of a second axis (y-axis). The optical beams propagate from input ports (3, 5 and 7) in a forward direction and are reflected from a liquid crystal on silicon (LCOS) device (11) in a return direction to output port (9). The input optical beams are transmitted through a port selecting module (21), which provides polarization diversity to device (1) and provides capability to restrict optical beams returning from LCOS device (11) from being coupled back into input ports (3, 5 and 7).

    Abstract: A holographic display image projector system including an input light source for generating an at least partially coherent optical input beam and an imaging system for transforming an image representation in the Fourier domain into a corresponding holographic image in the spatial domain. The image projector includes a spatial light modulator having a reflective phase manipulating surface and being responsive to an electric control signal to generate a two-dimensional phase profile on the reflective phase manipulation surface to diffract the optical input beam into a diffracted beam having a plurality of diffraction components angularly separated in a first dimension. A coupling prism having a first surface positioned such that a first subset of the diffraction components is refracted through the first surface to the imaging system, wherein upon refraction, an angular separation of the first subset of diffraction components is increased by at least a factor of 2.
