摘要： 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 4π. 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.

摘要： Disclosed are super broadband circularly polarizing film materials and novels methods of fabricating and using the same. The circularly polarizing materials are made from a film of material, such as a CLC polymer having a cholesteric order, in which a liquid crystal material, such as a nematic liquid crystal material, is distributed in a non-linear fashion across the thickness of the film in a plurality of liquid crystal-rich and liquid crystal-depleted sites in the CLC polymer. The pitch of the helices of the CLC molecules in the polyermized CLC material varies in a non-linear (e.g. exponential) manner along the depth dimension (i.e. transverse to the surface) thereof. The resulting circularly polarizing materials have reflection and transmission characteristics over bands of operation approaching 2000 nm. Depending on the final spiral structure of the materials utilized, the CLC circularly polarizing materials reflect either left-handed or right-handed circularly polarized light.
