Abstract
A bistable optical micro-switch controls the routing of an optical beam. The micro-switch has at least one optical micro-element, which is stable through electrical power interrupts, for directing the optical beam. A change in the state of the optical micro-element is effected by a vertical micro-actuator, which is biased by a micro-spring. A micro-latch can be used to keep the tensed micro-spring from un-tensing when electrical power is interrupted. A micro-latch holds the micro-element in at least one mechanically tensed, stable state.
