An m&#xd7;n fan out device for receiving at least m=2 laser beams of different wavelengths and dividing the power of each laser beam into at least two other laser beams directed to at least one of n exit ports of the fan out device is disclosed.

Multi-beam multi-aperture optical beam steering module

Electro-optically operated transmitters containing a wave guide liquid crystal beam steering device in series of fine beam steering devices as well as electrically switchable mirror are disclosed. The wave guide beam steering device is constructed on a planar lightwave circuit that contains a plurality of liquid crystal switching elements intersecting a plurality of optical wave guides and one main wave guide that has a curvature for light propagation. The transceiver is capable of continuously steering multiple beams of light into separate independent directions with a field-of-regard close to 4&#x3c0;. The resulted optical transmitter device is motionless, polarization sensitive or insensitive, stable within the operational spectral region, and stable versus temperature. When an optical receiver is integrated, the transmitters become transceivers. The invention also includes the methods for manufacturing the wave guide beam steering device.
