Chromophores with optimized second-order optical nonlinearity to optical loss ratios are synthesized, poled with an electrical field, and coupled into hardened polymer matrixes. Acentric order, which is necessary for electro-optic activity, is optimized by the consideration of chromophore-chromophore electrostatic interactions as well as chromophore-poling field interactions and thermal collisi...

This study introduces a reversible optical fulladder. Also optical NOT and NOR gates are implemented through Electro-Absorption-Modulator / Photo Detector (EAM/PD) pairs, were utilized for fulfilling reversible R gate. Then, reversible fulladder was designed based on the proposed reversible optical R gate. The operation of the suggested fulladder was simulated using Optispice and it was fou...

We have developed novel optical micro-electro-mechanical systems, (MEMS) and nano-electro-mechanical, (NEMS) optical components for applications including imaging, switching, and optical integrated circuits. This paper provides an overview of current optical MEMS/NEMS research projects in our integrated photonics laboratory at UCLA. Three optical MEMS/NEMS devices: a large, 1 mm diameter, scann...

sour cherry and orange juice were successfully cryoconcentrated. novel clarification (electro-flotation and ultra-filtration) improved cryconcentration efficiency. ef-uf clarified sour cherry and orange juices were cryoconcentrated in three stages up to 34.52±0.14, 44.42±0.19, 52.44±0.13 and 28.43±0.16, 40.51±0.15, and 45.42±0.19° brix at -10˚c respectively. duncan's multiple range test was use...

we explore electro-catalytic properties of a system consisting of platinum and palladium nanoparticles dispersed over a nanotubular self-organized tio2 matrix. these electrodes prepared by electroess and microemulsion of palladium and palladium nanoparticles on to tio2 nanotubes, respectively. titanium oxide nanotubes were fabricated by anodizing titanium foil in ethylene glycol (eg) fluoride-c...

In the late 1980s and 1990s, researchers in industry and academia became captivated by so-called organic nonlinear optical (ONLO) materials, as is evident from SPIE Proceedings of that period. The ultrafast response of the π-electrons of ONLO materials to time-dependent electric fields—which translates into active control of light—clearly afforded a unique opportunity vis-à-vis ultrahigh (terah...

Abstract In this study , palladium nano-particles were electro deposited galvano - statically on carbon black powder (Vulcan XC -72R). The catalytic activity for electro - oxidation of ethanol and methanol in alkaline media were studied by cyclic voltammetry and linear sweep voltammetry techniques. The results indicated that the electro-oxidation of ethanol and methanol strongly depends o...

The EODES suite of electro-optical system models is designed to provide a high-fidelity simulation capability and accurate performance prediction tools. EODES simulations are being used to analyze the performance of existing electro-optical identification (EOID) systems and to inform new system design concepts. Performance prediction tools are being incorporated into tactical decision aids with...

The nature of electro-optical equipment in various industries and the pursuit of the goal of reducing costs demand high reliability on the part of electro-optical systems. In this respect, reliability improvement could be addressed through a reliability allocation problem. Subsystem reliability must be increased such that the requirements as well as defined requisite functions are ensured in ac...
