摘要： A multi-port Wavelength Selective Switch (WSS), having a beam steering array to switch input light from one port into any one of a stack of output ports, but with the switch functionality doubled by using a polarization switching architecture which can deflect any of the switched beams in a plane perpendicular to the beam steering plane used by the WSS array. By this means, the port count is doubled, by having two stacks of ports disposed side by side in the switch. The beams are deflected to the desired port level in either of the stacks by means of a beam steering assembly, such as a one-dimensional MEMS array, and at the same time, any beam deflected to any of the port levels can be directed to either of the stacks by means of polarization switching components operative to divert the beams laterally between the two stacks.

摘要： A 1xN 2 wavelength selective switch (WSS) configuration (50) in which switch elements are configured in a way that enables the input or output fibers to be arranged in a two-dimensional "2D" array (56). By employing 2D arrays of input/output channels (56), the channel count is increased from N to N 2 for wavelength selective switches. In one embodiment, in which the components are arranged as a 2- f imaging system, a one-dimensional "1D" array of mirrors (52) is configured such that each mirror has a dual scanning axis i.e., each mirror can be scanned in X and Y directions. In another embodiment, in which the components are arranged as a 4- f imaging system, two 1D arrays of mirrors are configured with orthogonal scanning directions. In both embodiments, the number of ports is increased from N to N 2 .

摘要： A system for coupling up one or more light sources to one or more destinations is provided. Under the present invention, the transmission efficiency from a light source to a destination is optimized regularly on an automatic basis by monitoring the intensity of the light transmitted. In a preferred embodiment, the system includes a source fiberoptic cable for bundling up light emitted from a multitude of light sources, a destination fiberoptic cable for receiving light transmitted from the source fiberoptic cable, a motorized positioning stage for aligning the source and the destination fiberoptic cables, and a feedback servo control for adjusting the motorized positioning stage to accurately align the source and the destination fiberoptic cables based on the intensity of the light transmitted by the source fiberoptic cable. In operation, the intensity of the light transmitted by the source fiberoptic cable is detected by the feedback servo control. Based on the intensity reading, the feedback servo control selectively directs the motorized positioning stage to align the source and the destination fiberoptic cables in an optimal position to improve transmission efficiency.

摘要： An optical device includes an optical port array, an optical arrangement, a dispersion element, a focusing element and a programmable optical phase modulator. The optical port array has at least one optical input port for receiving an optical beam and a plurality of optical output ports. The optical arrangement allows optical coupling between the input port and each of the output ports and prevents optical coupling between any one of the plurality of optical output ports and any other of the plurality of optical output ports. The dispersion element receives the optical beam from the input port after traversing the optical arrangement and spatially separates the optical beam into a plurality of wavelength components. The focusing element focuses the plurality of wavelength components. The programmable optical phase modulator receives the focused plurality of wavelength components and steers them to a selected one of the optical outputs.

摘要： A fiber optic sensor for detecting acceleration or displacement includes a fiber optic probe with a multimode transmitting optical fiber, a multimode receiving optical fiber and a edge reflector spaced apart from the fiber probe. The reflector moves in a transverse direction substantially normal to the longitudinal axis of the fiber optic probe, so the amount of light received by the receiving fiber indicates a relative acceleration or a relative displacement of the reflective surface with respect to the fiber probe in the transverse direction of motion of the edge of the reflector. The reflector can be mounted on a cantilever beam. The sensor can have one transmitting fiber, two receiving fiber, and a reflector with two edges, each edge partially covering one of the receiving fibers. A triaxial sensor system has at least two two-fiber sensors.
