Electro-optic polymers have unique photonic, electro-optic and mechanical properties that make them attractive to use in a wide range of devices starting from ultra-high bandwidth light modulators for optical communications to miniature low power components for on-chip optical interconnects. The main building blocks of those devices are optical waveguides, that due to versatility of the polymer...

A novel reprogrammable optical phase array (ROPA) device is presented as a reconfigurable electro-optic element. One specific application of the ROPA, a 1 x 6 electro-optic space switch, is fully described. Switching angles are within 2 degrees , and switching is achieved through a complementary metal-oxide semiconductor (CMOS) controlled, diffraction based, optical phase array in a bulk BaTiO3...

Accurate visibility forecasts, being necessary for military operations and field applications of opticallysensitive equipment such as advanced electro-optical (EO) systems, remain as a challenging scientific problem. One reason is because large spatial and temporal variations exist, not only with aerosol physical and optical properties, but with emission sources. Clearly, to further advance aer...

In recent years there has been a lot of interest in the development of optical processing elements for optical computing and neural networks. These devices are expected to exploit the high parallelism possible with optical systems. Several candidates have been proposed and demonstrated but it is still not clear which, if any, will be the clear leader in providing a cheap, reliable optical switc...

We have developd new techniques that enable characterization of ultrafast optical waveforms generated via spectral line-by-line pulse shaping under the Optical Arbitrary Waveform Generation (O-AWG) program. Our approaches simultaneously address a number of challenging requirements not met by existing waveform measurement methods, including high waveform complexity, high spectral resolution, and...

Electro-optical implementation of a three-dimensional (3-D) spatial correlation is proposed. A 3-D scene of objects, seen from the paraxial zone, is correlated with a reference object. As an example of application, we describe a 3-D joint transform correlator that is capable of recognizing targets in the 3-D space. © 1998 Optical Society of America [S0740-3232(98)02102-4] OCIS codes: 070.2590, ...

We propose a method for measuring the terahertz properties two principal optical axes of anisotropic crystals without activity using time-domain spectroscopy (THz-TDS). The put forward in this paper utilizes inherent polarization sensitivity THz-TDS electro-optic detection system. demonstrate practical application by temperature dependence refractive index and absorption coefficient lithium tri...

We observe the phenomenon of the Faraday-like effect, which occurs in periodically poled lithium niobate with odd number of domains (OPPLN) by the transverse electro-optic (EO) effect under the quasi-phase-matching condition. In this case, light rotates in the reverse sense during the forward and the backward path, and OPPLN shows a nonreciprocal process that is similar to the magneto-optical F...

Quadratic electro-optic effects (QEOEs) and electro-absorption (EA) process in a GaN/AlGaN spherical quantum dot are theoretically investigated. It is found that the magnitude and resonant position of third-order nonlinear optical susceptibility depend on the nanostructure size and aluminum mole fraction. With increase of the well width and barrier potential, quadratic electro-optic effect and ...
