Scientific Fields and Expertise

  1. Multimode quantum memory based on Lambda-atoms. High-speed quantum memory.
  2. Optical Parametric processes in continuous variables: optical parametric amplifier (OPA) and optical parametric oscillator (OPO), investigation of three-mode statistics OPO above threshold, multimode squeezed radiation of sub-Poissonian laser and degenerate OPO.
  3. Quantum dense coding protocol for optical images: dense coding scheme for continuous variables, multimode in space and time optical quantum communication channel, parallel dense coding of non-stationary optical images, the Shannon mutual information, superior to the standard quantum limit.
  4. Induced photon statistics: we have proved that under the specific conditions, the photon statistics of the three-level laser duplicate the photon statistics of the exciting laser. Application of this phenomenon to analyze the statistical properties of a laser involved into a feedback process.
  5. Elaboration of the quantum fluctuation theory of vertical-cavity surface-emitting lasers (VCSEL's): quantum Stokes parameters, quantum self- and cross correlations, fluctuation spectra, polarization squeezing, sub-Poissonian statistics. Application of the theory to VCSEL's with equally-lived laser levels, a role of physical phenomena such as spin-flip and optical anisotropy (linear birefringence and linear dichroism). Analysis of stability of linearly polarized lasing modes.
