Abstract
In one embodiment, a method of aligning mirrors of a micro-electro-mechanical system (MEMS) photonic switch includes illuminating a first group of photodiodes associated with a first mirror of a first mirror array of the MEMS photonic switch by a first control beam during a first period of time and illuminating a second group of photodiodes associated with a second mirror of the first mirror array by a second control beam during a second period of time, where the second control beam is off during the first period of time, where the first control beam is off during the second period of time, and where the second period of time is after the first period of time. The method also includes illuminating the first group of photodiodes by the first control beam during a third period of time, where the second control beam is off during the third period of time, and where the third period of time is after the second period of time.
