Wavelength rigidly fixes the diffraction that distorts waves during propagation, and poses
fundamental limits to imaging, microscopy and communication. This distortion can be …

As atoms and molecules condense to form solids, a crystalline state can emerge with its
highly ordered geometry and subnanometric lattice constant. In some physical systems …

Studies of the electrooptic effect in potassium tantalate niobate (KTN) and Li doped KTN in
the vicinity of the ferroelectric phase transition are reported. It was observed that in KTN the …

Electroholographic switching with a rise time of 13 ns is henceforth presented. The switching
was demonstrated in a potassium lithium tantalate crystal doped with copper and titanium …

We investigate the evolution of the state of polarization of light propagating through bulk
depoled composite ferroelectrics below the Curie temperature. In contrast to standard …

A generic methodology for constructing complex integrated electro-optic circuits in
waveguided configurations is presented. The method is based on combining two …

Paraelectric potassium–lithium–tantalate–niobate, or KLTN, crystals have been grown with
two different Mn concentrations: 0.25 and 0.5 mol%. Detailed investigations have been …

We report the successful growth of paraelectric potassium lithium tantalate niobate (KLTN)
single crystal doped with iron. Detailed investigations have been made on the …

Volume phase gratings have been fabricated by controlled generation of periodic striations
during the growth of copper doped potassium lithium tantalate niobate crystals. Gratings with …

An electrooptical channel waveguide array was constructed in potassium lithium tantalate
niobate substrate by the implantation of He^+ ions at high energies. The array was …
