A fiber-optic voltage sensor based on the longitudinal Pockels effect in a Bi(12)TiO(20) crystal is described. The use of a special backreflecting prism as a phase-retarding element is shown to improve the sensitivity and temperature stability of the sensor. A comparison between the temperature properties of the glass backreflecting prism and that of a quarter-wave plate is derived. The sensor ...
Precise measurements of electrostatic fields in harsh environments are required ranging from particle accelerators to industrial installations. Many techniques disrupt the field distribution due presence conductors. We present a fully dielectric sensor for very environmental conditions, that exploits Pockels effect manifested by electro-optic crystals. This system is designed allow DC be perfor...
Liquid-crystalline polymers are materials of considerable scientific interest and technological value. An important subset of these materials exhibit rubber-like elasticity, combining the optical properties of liquid crystals with the mechanical properties of rubber. Moreover, they exhibit behaviour not seen in either type of material independently, and many of their properties depend crucially...
The purpose of this note is to introduce the linear electro-optic effect (Pockels effect) and its applications for modulating the properties of a light wave, such as its phase, polarisation and intensity. For this purpose, basic electromagnetic theory is first reviewed. Some elements of light propagation in an anisotropic medium are then introduced. The linear electro-optic effect is then prese...
This paper discusses important elements of the Pockels sensing cell design. A novel electrode geometry is analyzed in order to obtain maximum sensitivity response from Pockels crystals (Bi(12)GeO(20)). This neither transversal nor truly longitudinal geometry, results in electrical field distribution along the sensing beam path that provides high modulation depth. Demonstrated performance level ...
An electro-optic modulator offers the function of modulating propagation light in a material with an electric field and enables seamless connection between electronics-based computing photonics-based communication. The search for materials large coefficients low optical loss is critical to increase efficiency minimize size devices. We present semi-empirical method compute ferroelectric by combi...
All three LIGO detectors have reached their design sensitivities. A sky-averaged detection range (SNR > 8) of more than 15 Mpc for inspiral binary neutron stars with masses of 1.4 Msol has been achieved with the two 4 km instruments. The fifth LIGO science started in November 2005 and ended September 2007. About 365 days of coincidence data have been collected. The feedback controls system is a...
