Abstract:
A MEMS VOA for attenuating an optical signal, the optical signal transmitted via a light beam, and the MEMS VOA comprising:a substrate; a movable focusing mirror, the movable focusing mirror coupled with the substrate, and the movable focusing mirror for reflecting, focusing and steering the light beam in a trajectory; an actuator, the actuator coupled with the substrate, and the actuator operatively coupled with the movable focusing mirror, the actuator for actuating the movable focusing mirror; an input photonic component, the input photonic component coupled with the substrate, and the light beam emitting from the input photonic component and toward the movable focusing mirror; and an output photonic component, the output photonic component coupled with the substrate and positioned to receive at least part of the light beam reflected from the movable focusing mirror when the light beam is steered towards the output photonic component.
