Abstract
An optical port with directional control. The port includes a transmitter, receiver, and first actuator. The transmitter generates an outgoing light signal that propagates in a transmission direction in response to an outgoing electrical signal. The receiver receives an incoming light signal and generating an incoming electrical signal therefrom, the receiver having a reception direction aligned with the transmission direction. The first actuator alters the transmission direction of the outgoing light signal in response to a first control signal. In one embodiment, the first actuator determines the direction of the outgoing light signal in a first plane, and a second actuator controls the direction of the outgoing light signal by an amount determined by a second control signal. The second actuator controls the direction of the outgoing light signal in a second plane that is orthogonal to the first plane. The actuators can be constructed from beam deflectors that utilize moveable mirrors to alter the transmission direction. In one embodiment, the deflector includes an array of mirrors, each mirror rotating about an axis through the mirror. Actuators that rotate the transmitter and reflector may also be utilized.
