We develop the asymptotic theory of third-harmonic generation from silicon nanoparticles driven by optically-induced Mie resonances and analyze the multipolar nature of the generated electromagnetic fields. We propose the approaches for directing the resonantly enhanced nonlinear scattering by spherical and disk-shaped particles, excited in the vicinity of the magnetic dipolar resonance. Our analytical...
The next generation of optical networks requires the development of optical technology that supports high bandwidth, such as the coherent systems. The coherent detection allows the in-phase and quadrature components of a QPSK signal to be extracted as a result of the interference with a local oscillator. An integrated optics flexible 90° hybrid coupler device based on a single organic-inorganic di-ureasil...
The insertion of mobile ions and coupled changes of electron concentration are exploited to induce a non-volatile and reversible change of the optical properties of mixed ionic and electronic conductors (MIECs). The physical mechanisms responsible for the change of the real and imaginary part of the MIECs' refractive index upon ion-intercalation are extensively investigated in the visible and near-IR...
Active and passive optical waveguides are fundamental elements in modern telecommunications systems. A great number of optical crystals and glasses were identified and are used as good optoelectronic materials. However, fabrication of waveguides in some of those materials remains still a challenging task due to their susceptibility to mechanical or chemical damages during processing. Ion beam has...
