We developed a way of predicting and analyzing high speed optical modulator. Our research adopted a bottom-up approach to consider high-speed optical links using an eye diagram. Our method leverages on modular “mapping” of electrical characteristics to optical characteristics, while attaining the required accuracy necessary for device footprint approaching sub-micron scales where electrical dat...

Among several optical devices in integrated optics, the fundamental characteristics of collinear optical switching devices have been studied about optical dielectric waveguides. Conventional waveguidetype acousto-optic (A-O) devices use collinear and longitudinal interactions with mode coupling based on the Bragg condition between optical waves and surface acoustic waves (SAW). Collinear A-O de...

Abstract Recent work has confirmed that radially-polarised optical modes, specifically those endowed with helical wave fronts can now be routinely generated in the laboratory. Here we show such a paraxial mode carries only an axial total angular momentum (AM) where $\ell$?> ...

Исследованы нелинейно-оптические характеристики Cr4+:YAG кристалла методикой Zсканирования по схеме с открытой апертурой. В качестве пробного источника использовано излучение непрерывного лазера на длине волны 1030 нм мощностью до 400 мВт. При этом наблюдалось нелинейное поглощение лазерного излучения, которое связано снасыщением возбужденного состояния кристалла. Определена интенсивность насыщ...
