Abstract
Methods of operating an optical circuit switch and optical circuit switches are disclosed. 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.
