Generation of broadband single-photon states in photonic-crystal fibers with flattened dispersion profiles
The features of modelling semiconductor lasers with a wide contact
The aspects of calculating the dynamics and statics of powerful semiconductor laser diodes radiation are investigated. It takes into account the main physical mechanisms influencing power, spectral composition, far and near field of laser radiation. It outlines a dynamic distributed model of a semiconductor laser with a wide contact and possible algorithms for its implementation

Amplification of surface plasmon polariton wave in single-walled carbon nanotube using electric current pump
Subcarrier Wave Quantum Key Distribution in Telecommunication Network with Bitrate 800 kbit/s
In the course of work on creating the first quantum communication network in Russia we demonstrated quantum key distribution in metropolitan optical network infrastructure. A single-pass subcarrier wave quantum cryptography scheme was used in the experiments. BB84 protocol with strong reference was chosen for performing key distribution. The registered sifted key rate in an optical cable with 1.5 dB loss was 800 Kbit/s. Signal visibility exceeded 98%, and quantum bit error rate value was 1%. The achieved result is a record for this type of systems
