Abstract
In a variable optical attenuator (VOA) and a method of variably optically attenuating a light beam, a input lens receives an input light beam and an output lens outputs an output light beam. A mirror reflects the input light beam as the output light beam. The mirror or a moveable element is movable in a manner to block, pass, and/or reflect at least a portion of the light included in the input light beam and the output light beam, whereupon the output light beam has reduced or increased brightness or intensity versus the input light beam.
