Abstract: PROBLEM TO BE SOLVED: To solve the problem that an MEMS system mirror array is required which has mirror surfaces each having an effective area smaller than the steering range of the surface in order to perform signal routing, and the MEMS mirror array is necessary which requires a control signal lower than 150 V to position each mirror surface when performing the signal routing. SOLUTION: An optical element 70 to perform routing of a plurality of optical signals between a first port and a second port is provided. The optical element 70 includes a mirror array 75 having a plurality of reflectors. Each optical input signal 72 is sent out by reflectors 82 and 84 in a direction specified by control signals. The optical element 70 includes, moreover, curved mirror planes 82 and 84 which receive optical signals 72" sent out respectively from each reflector, and reflect the optical signals sent out to the first or second port, respectively.

Abstract: PROBLEM TO BE SOLVED: To provide a full optical switching which does not increase the number of micromirrors used to implement a switching function and uses an MEMS device. SOLUTION: Using an imaging system, the optical MEMS device is imaged so that in combination with an actual one or more other optical MEMS devices, or images thereof, a single virtual optical MEMS device is formed that has the size of each of the optical MEMS devices combined. The physical size of the arrangement may be reduced by compacting the optical path, e.g. using appropriate conventional mirrors, and/or employing folded arrangements, i.e., arrangements in which there is only one MEMS device stage that does double duty for both input and output through the use of at least one conventional mirror.

Abstract: PROBLEM TO BE SOLVED: To provide optical monitoring for optical cross connection fabric. SOLUTION: This optical cross connection (OXC) fabric to be constituted of arrangement of inclinable mirrors, a reflector and plural optical fibers controls positions of mirrors by monitoring optical signals at a position of an optical translation unit corresponding to each of an inputted optical fiber and an outputted optical fiber and thus, optimizes signal transmission between the inputted optical fiber and the outputted optical fiber. The optical translation unit has a function to reproduce the optical signal transmitted in a fiber as well.

Abstract: PROBLEM TO BE SOLVED: To provide an opto-isolator for selectively carrying an optical signal along an optical path from a signal source to a detector separate from the signal source. SOLUTION: The opto-isolator 10 incorporating an MEMS device 16 includes the optical signal source 12 and the optical signal detector 14 fixed while putting the optical path for communicating the optical signal in between. The device 16 having an actuator 22 for controlling a movable element 18 is provided between the signal source 12 and the detector 14 in order to operate the optical signal. In one embodiment, the element 18 is a shutter selectively making the detector 14 receive the optical signal and acting to prevent the signal from being detected. In another embodyment, a movable member is an MEMS inclined mirror for selectively making the optical signal go toward the detector 14.

Abstract: PROBLEM TO BE SOLVED: To realize a double port waveguide grating router which has an essentially flat pass band, which greatly reduces loss penalty added by an external coupler or which has almost no such loss. SOLUTION: The double-port waveguide grating router is provided with a first free space area for receiving an optical signal from at least one input waveguide, an optical grating consisting of plural waveguides, a second free space area and plural output waveguides. These plural output waveguides are provided with at least two adjacent waveguides, with a two input 2×2 coupler connected to the two adjacent waveguides, and with the output port of this 2×2 coupler serving as the output port of the waveguide grating router. The double-port waveguide grating router realizes an essentially identical specifiable pass band in the two output ports.

Abstract: PROBLEM TO BE SOLVED: To provide a micro electromechanical system optical device having a reduced occupied area. SOLUTION: In order to increases the production quantity on a substrate, the micro electromechanical system (MEM) optical device has the reduced occupied area. The MEM device has the optical element which has an outer edge and is supported by a supporting structure body disposed at the substrate. The supporting structure body is mechanically connected to the substrate by the pair of first and second beam which moves the structure to the startup position at which the optical element is raised upward of the substrate. At the raised position, the optical element is selectively inclined in order to deflect an optical signal. The beam is connected at one end to the supporting structure body, and is connected at the other end to the substrate, and the edge of the first and the second beam is placed so that they may be approached and located in the outer edge of the optical element. In order to decrease the contact area between the edge of the optical element and the substrate, it is suitable that a static frictional force reduction element is located in the outer edge of the optical element.

Abstract: PROBLEM TO BE SOLVED: To provide a method and a device which detect rotation drift of a mirror element in a MENS inclined mirror array used in an optical cross connection device. SOLUTION: In the optical cross connection device, by arranging the mirror element in a desired position while rotating it, an optical signal from an input fiber is directed toward an output fiber along an optical path. A monitor device arranged on the outside of the optical path is used to obtain a picture of a MENS array or transmit and receive a test signal through the cross connection device in order to detect the existence of mirror element drift.

Abstract: PROBLEM TO BE SOLVED: To realize both an add/drop function and an add and continue function for WADM node of an optical communication network at the same time. SOLUTION: This invention provides a configuration including two duplicate port waveguide grating routers(WGR) and a plurality of attenuation switches. The one WGR is configured as a 1×2N demultiplexer and the other as a 2N×1 multiplexer. Each WGR includes a plurality of duplicate input or output waveguides and the respective pairs have nearly the same spectral characteristic. The 1st output waveguides of the 1st WGR are connected to the input waveguides of the 2nd WGR and the attenuation switches are provided between them to cut off a specific wavelength. The 2nd output waveguide of the 1st WGR act like drop waveguide and the 2nd waveguides of the 2nd WGR act like add waveguides to realize the add/drop function.

Abstract: In a system and method of optical communication, optical signals are generated in multiple wavelength channels. Each optical signal is passively transported from an origination node of a network to a destination node. The destination node is determined by the signal wavelength. For at least some signals, the passive transport includes transport through a branch point of the network, such that the signal wavelenth determines the output branch through which the signal is routed. In certain embodiments, signals are generated according to a schedule devised to substantially prevent the concurrent arrival, at the same destination node, of signals having the same wavelength but coming from different origination nodes.
