Abstract
An optical circuit switch and method. A first mirror element rotates about orthogonal axes in response to first and second voltages applied respectively to first and second electrodes. A second mirror element rotates about orthogonal axes in response to third and fourth voltages applied respectively to the third and fourth electrodes. A controller may apply first through fourth voltages respectively to the first through fourth electrodes to make a connection between first and second ports. When an initial insertion loss of the connection does not exceed a predetermined threshold, the controller may conduct independent single-dimension searches to determine values for the first through fourth voltages that minimize the insertion loss. When the initial insertion loss exceeds the predetermined threshold, the controller may conduct a four-dimensional search to determine values for the first through fourth voltages that reduce the insertion loss to not exceed the predetermined threshold.
