Abstract
An opto-isolator incorporating a MEMS device includes an optical signal source and an optical signal detector defining therebeween an optical path for communication of optical signals. A MEMS device having an actuator for controlling a moveable element is disposed between the source and detector for manipulating the optical signals. In one embodiment, the moveable element is a shutter which is operable to selectively allow optical signals to be received by the detector and prevent signals from being detected. In another embodiment, the moveable member is a MEMS tilt mirror for selectively directing optical signals to the detector.
