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.pi.. 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.
