  • Optical assembly with variable optical attenuator
    Publication number: 20050109923
    Abstract: An optical assembly includes a photodetector for detecting light signals. An optical fiber receives an input signal and has a light-emitting portion extending in front of the photodetector. A MEMS actuator is located between the light-emitting portion of the optical fiber and the photodetector. The MEMS actuator is controllably deflectable to partially obscure the photodetector and thereby vary the amount of light received.
