In this paper we propose a new method for the determination of the distribution of electrical and geometrical particle parameters based on electrooptical experimental data. The electrooptical method leads to the solution of inverse ill-posed problems. The main equations for the determination of the distribution of particles on these parameters are presented. To find out the distribution functio...
This paper reports on the optical generation of a rapidly tunable millimeter-wave subcarrier for lidar–radar. The millimeter-wave signal is generated by beating the output from two Nd : YVO4/MgO : LiNbO3 electrooptical monomode microchip laser sections realized monolithically in a single composite crystal. The device has a continuous tuning range up to 45 GHz. The measured chirp rate is 3816 TH...
Chiral smectic liquid crystal cells showing V-shaped electrooptical switching have been reported as one of the most promising technologies for high-end display applications. In this work, time-resolved electrical behaviour of these devices has been obtained through a set of systematic measurements. The electrical equivalent circuit has been derived, a number of simulations at different frequenc...

Nonlinear optics is a broad field of research and technology that encompasses subject matter in the fields of physics, chemistry, biology, and engineering. The diversity of nonlinear optics stems, in part, from the need for all-optical and electrooptical devices for applications in telecommunications, optical storage, and all-optical computing. In addition, many nonlinear optical effects have p...
Polymer-dispersed liquid crystals (PDLCs) represent an important new class of materials for optical device applications. Their valuable advantages such as low operating voltage, high contrast ratio, requiring no extra optical elements (i.e. polarizer), quick electrooptical response, no leakage of materials, simple fabrication, low-cost production and ease of processing make them more popular ov...
Nowadays, chemically synthesized proteins and peptides are attractive building blocks and have potential in many important applications as biomaterials. In this review, applications of biomaterials to thermotropic liquid crystals are discussed. The review covers the improvement of the performance of liquid crystal displays using liquid crystal physical gels consisting of a liquid crystal and am...
