The Movie: RQPM autocorrelator pattern variation with pulse delay

The Movie: RQPM autocorrelator pattern variation with pulse delay.

Research focus:

  • Optical and spectral properties of photonic crystals (PCs)
  • Controllable PCs (electromagnetically induced transparency and Raman interaction)
  • PCs with liquid-crystal inclusions
  • Resonance PCs
  • Nonlinear PCs
  • Fast and slow light
  • Nonlinear optical processes in metamaterials
  • Nanocolloids: structural self-organization and interaction with optical radiation
  • Study of the structural phase transformations in solid-state reactions and atomic ordering in thin films by transmission electron microscopy, high-resolution electron diffraction, and X-ray diffraction microanalysis
