Abstract:

Sterically stabilized second-order nonlinear optical chromophores and devices incorporating the same are embodied in a variety of chromophore materials. An exemplary preferred chromophore includes an electron donor group, an electron acceptor group and a bridge structure therebetween, with the electron acceptor group being double bonded to the bridge structure. In a preferred embodiment, the bridge structure also includes at least one bulky side group. Another exemplary preferred chromophore includes an electron donor group, an electron acceptor group and a ring-locked bridge structure between the electron donor group and the electron acceptor group. The bridge structure comprises, for example, two protected alicyclic rings or ring-locked trienone. Another exemplary preferred chromophore includes an electron donor group, a ring-locked tricyano electron acceptor group, and a bridge structure therebetween. In a preferred embodiment, the electron acceptor group comprises an isophorone structure.

US Classification:

333156, 385 3, 385 8, 385 9, 359237, 359238

Abstract:

A power balanced photonic RF phase shifter includes: a microwave drive; a phase controller operably connected to the microwave drive; and a linearizing arm connected in parallel with the microwave drive, the linearizing arm operating under a bias voltage, V, that is controlled such that power variations of the photonic RF phase shifter are mitigated. In a preferred embodiment, the bias voltage, V, is controlled to keep an optical phase of the photonic RF phase shifter at a constant value. In a preferred embodiment, the microwave drive, the phase controller and the linearizing arm comprise (three) Mach-Zehnder modulators.

International Classification:

G08G 100

US Classification:

340436

Abstract:

A phased array based radar and vehicular safety warning system for collision avoidance, including a phased array based radar, a controlling processor, and a warning system that also provides a warning to the driver of the equipped vehicle as well as drivers of other, non-equipped automobiles involved in an unsafe driving condition. The phased array radar includes a flexible antenna array that may be mounted conformally on existing automobiles without detracting from their design curvature. In one embodiment a pair of phased array radar antenna may be oriented towards opposing sides of an equipped automobile to provide warning surveillance of vehicles laterally approaching the equipped auto from the sides. In another embodiment a phased array radar antenna is oriented to the rear of the equipped automobile to provide warning surveillance of vehicles following the equipped auto too closely, and for warning of unsafe lane changes. In still another alternative embodiment a pair of phased array radar antenna having 180. degree.

US Classification:

359321

Abstract:

A new class of high hyperpolarizability organic chromophores and a process for synthesizing the same. The chromophores incorporate at least one organic substituent and are formed in consideration of molecular shapes and a spatial anisotropy of intermolecular interactions. The chromophores are processed into hardened material lattices to lock-in poling induced electric-optic activity. Preferred organic substituents are alkyl, aryl, and isophorone groups. A composite including the organic chromophore, in a preferred embodiment, includes a polymer such as a poly(methylmethacrylate), polyimide, polyamic acid, polystyrene, polycarbonate or polyurethane. The optimized chromophores result in hardened electro-optic polymers suitable for electro-optic modulators and other devices such as optical switches. These modulators can be configured to work at high frequencies and in arrays for applications in communications and network connections. In addition, they can be implemented in series and parallel combinations in phased array radar, signal processing and sensor technology applications.
