Abstract
Methods of operating an optical circuit switch and optical circuit switches are disclosed. An optical circuit switch may receive a first make command to make a first optical connection between a first port and a second port, the first port uniquely associated with a rotatable mirror element, determine a first baseline voltage to be applied to an electrode coupled to the mirror element to cause the mirror element to rotate about an axis to make the first optical connection, and apply the first baseline voltage to the electrode. The optical circuit switch may periodically adjust the voltage applied to the electrode to minimize an insertion loss of the first optical connection, and periodically store accumulated angular drift data in a memory, the accumulated angular drift data derived from a difference between the adjusted voltage applied to the first electrode and the first baseline voltage.
