Abstract
This disclosure provides systems, methods, and apparatus for a MEMS mirrors based optical circuit switch. The optical circuit switch includes digital to analog converter (DAC) for converting digital position codes into analog mirror position signals. A mapper transforms the analog mirror position signal into a mapped mirror position signal. The mapped mirror position signal is provided to a MEMS actuator that positions the MEMS mirror based on the mapped mirror position signal. The mapper transforms the analog mirror position signal into the mapped mirror position signal such that the MEMS mirror position has a substantially linear relationship with the analog mirror position signal provided by the DAC.
