The realization of efficient and miniature source of entangled photon pairs stills remains a challenge. In this work, we experimentally studied the possibility to enhance the process of spontaneous parametric down-conversion by surface plasmon polari

We carried out a laser spectroscopic investigation of high-pressure, high-temperature (HTHP) synthetic diamond containing NE8 defects. In the photoluminescence (PL) emission spectra the defects have a zero-phonon line (ZPL) at 794 nm. Under 730 nm ex

Composite TiO 2 layers with embedded Au-nanoparticles with a size of 8–20 nm were deposited in situ by chemical spray pyrolysis. EDS studies show that increase in the deposition temperature from 260 to 300 °C decreases the [Au]/[Ti] ratio down to

The emission of photon pairs by a metal–dielectric interface placed between the mirrors of the resonator and excited by a plane wave is considered. The excitation causes oscillations in time of the optical length of surface plasmon polaritons in th

We demonstrate experimentally that the electrophoretic manipulation of a ZnO nanowire (NW) suspension in polydimethylsiloxane (PDMS) causes a remarkable change in optical scattering. Counterintuitively, as an electric field is applied to the suspensi

A spontaneous emission of photon pairs in the metal–dielectric interface or waveguide, placed to a resonator and excited by laser light, is considered. The emission results from the laser-induced oscillations of the optical length of modes in reson
