Claim:
An optical switch comprising: a first binary control element having a first angle tuning element that is moveable between a first position and a second position; and a second binary control element in series with the first binary control element and having a second angle tuning element that is moveable between a third position and a fourth position, wherein the first binary control element is configured such that, in the first position, the first angle tuning element is able to adjust a pathway of an optical signal, in the second position, the first angle tuning element is removed from the pathway of the optical signal and therefore not able to adjust the pathway of the optical signal, and the second binary control element is configured such that, in the third position, the second angle tuning element is able to adjust the pathway of the optical signal and, in the fourth position, the second angle tuning element is removed from the pathway of the optical signal and therefore not able to adjust the pathway of the optical signal.
