The generation of interband photon pairs with wavelengths near 0.5 and 1.6 μm in a photonic-crystal fiber under low-power cw optical pumping by diode laser central wavelength 0.8 has been experimentally demonstrated. It found that the rate entangled photons is comparable values obtained pulsed femtosecond Ti:sapphire if average pump power an order magnitude higher than power. reached rates are ensured used small effective mode area special dispersion profile. low noise output signal...
In this Letter, we report a first, to the best of our knoqledge, experimental realization bright ultra-broadband (180 THz) fiber-based biphoton source with widely spectrally separated signal and idler photons. Such two-photon is realized due joint use broadband two-loop phase-matching interacting light waves high optical nonlinearity silica-core photonic crystal fiber. The performance developed fiber identifies it as an important useful tool for wide range quantum applications.

This article describes researching the dynamic retaining capacity of existing regular packings for mass-transfer apparatuses. As a result this research an improved design packing with lower power was developed.
An actual task of quantum communications over long distances is the creation a bright source photon pairs operating at standard wavelengths fiber optic communication lines. In this work, we experimentally investigated spectral and correlation characteristics generated on phenomenon spontaneous four-wave mixing in highly nonlinear photonic-crystal with wavelength one photons near 1.5 μm. The demonstrated can be used as an efficient single generator telecommunications prediction tuning wide range.
