摘要： An optical device incorporates into the same physical structure the functionality of two or more wavelength selective switches. The wavelength components associated with the first optical switch are isolated from the wavelength components associated with the second optical switch by their spatial displacement along one axis on a programmable optical phase modulator. Remaining crosstalk between the components is reduced by spatially separating the components of the two wavelength switches having the same wavelength along another axis of the programmable optical phase modulator.

摘要： An optical switch is configured in a “dual-ganged” switch geometry to provide for the simultaneous switching of a selected transmit/receive pair of optical signal paths between a specific optical communication device and an optical communication network. A biaxially-symmetric signal redirection component may be used to direct the signals between the selected channel and the optical communication device. A specific waveguide (e.g., fiber) array topology within the dual-ganged switch (DGS) breaks the symmetry between the network transmit/receive arrays and a pair of transmit and receive signal paths associated with the communication device to improve isolation and minimize the possibility of cross-talk between non-selected waveguides in the transmit and receive arrays. The possibility of “hits” during switching between channels can be eliminated, and is controlled by dictating the process or switching steps used to rotate the biaxially-symmetric signal redirection element.

To make a connection between a first port and a second port, baseline voltages may be determined, baseline voltages being voltages that, if respectively applied to one or more electrode coupled to a first mirror element uniquely associated with the first port and one or more electrode coupled to a second mirror element uniquely associated with the second port, cause the first and second mirror elements to rotate to make the connection in the absence of accumulated mirror element drift. Accumulated drift data associated with one or both of the first mirror element and the second mirror element may be retrieved from a memory. One or more of the baseline voltages may be modified based on the accumulated drift data to provide corrected voltages, and the corrected voltages may be applied to the electrodes.

摘要： A method for compensating for a wavelength shift in a wavelength selective switch (WSS), and a device therefor. The device comprises a fixed seat (301) as well as a rotation beam (304) and a compensation block (302) that have different thermal expansion amounts, the rotation beam (304) and the compensation block (302) being fixedly adhered to the fixed seat (301). In the method, a combined structure of the rotation beam (304) and the compensation block (302) with different thermal expansion amounts is adopted; the combined structure rotates by means of different expansion amounts generated by the rotation beam (304) and the compensation block (302) at the same external temperature, and further drives an optical element of the WSS to rotate, hence compensating for a wavelength shift of the WSS. The method is safe and reliable; the device has a simple structure, and is convenient to encapsulate, is applicable to various WSS optical paths, and does not affect advantages of the optical path structure of the WSS.
