The only solutions at present offered for the problem of reproducing television pictures in dimensions comparable with those of the cinema screen all of them involving projection are complicated and often very costly. , In the first part of this article, we shall examine a number of solutions proposed or already in use. In the second part, a real-time system will be described which is based on ...

We present the realization of a ultra fast shutter for optical fields, which allows to preserve a generic polarization state, based on a self-stabilized interferometer. It exhibits high (or low) transmittivity when turned on (or inactive), while the fidelity of the polarization state is high. The shutter is realized through two beam displacing prisms and a longitudinal Pockels cell. This can re...

In the research on application of an optical modulator used for information communication, materials having a large Pockels effect, refractive index change proportional to electric-field, are required. It is known that interfacial water surface transparent oxide electrodes has giant coefficient, which order magnitude larger than solid crystals practically used. important know coefficient not on...

SrTiO3 epitaxial growth by molecular beam epitaxy (MBE) on silicon has opened up the route to the monolithic integration of various complex oxides on the complementary metal-oxide-semiconductor silicon platform. Among functional oxides, ferroelectric perovskite oxides offer promising perspectives to improve or add functionalities on-chip. We review the growth by MBE of the ferroelectric compoun...

The influence of optical parameters on the performance of closed-loop optical voltage sensors (OVSs) based on Pockels effect is analyzed and a control algorithm is proposed to suppress the nonlinearity caused by the unideal parameters of optical devices for optimizing the detection precision of OVSs. First, a quantified model of the feedback phase demonstrates how the optical parameters of opti...
