This work describes an experimental system for sensing and transmission of electric signals using optical coherence modulation of light. The system consists of a Ti:LiNbO3 optical coherence modulator acting as electric signal sensor. The main characteristics of coherence-modulated transmissions include the need of using broad-band optical sources and integrated optics lithium niobate electro-op...

In this study, we show the effect of various nanoparticle additives on phase separation behavior of a lattice-patterned liquid crystal [LC]-polymer composite system and on interfacial properties between the LC and polymer. Lattice-patterned LC-polymer composites were fabricated by exposing to UV light a mixture of a prepolymer, an LC, and SiO2 nanoparticles positioned under a patterned photomas...

The recent development of photonics and applications puts new challenges for systems using emission, transmission and modulation of light.

Ferroelectric oxides are a group of advanced electronic materials with a wide variety of properties useful in applications such as memory devices, resonators and filters, infrared sensors, microelectromechanical systems, and optical waveguides and modulators. Among the oxide perovskite-structured ferroelectric thin film materials, sodium potassium niobate or Na0.5K0.5NbO3 (NKN) has recently eme...

Evaluation of the performance of electro-optical payload within the laboratory is discussed. This method is valid for the system, which has output in the form of electrical signal though the input is optical in nature. The methodology enables the evaluation of entire configuration of electro-optical payload comprising of lens system, photo detecting device (one or two dimension array) and proce...

We demonstrate a novel mechanism for low power optical detection and modulation in a slotted waveguide geometry filled with nonlinear electro-optic polymers. The nanoscale confinement of the optical mode, combined with its close proximity to electrical contacts, enables the direct conversion of optical energy to electrical energy, without external bias, via optical rectification, and also enhan...

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...
