Research
1. Nonlinear optics in fibers and waveguides
This area of research includes ultrafast nonlinear processes such as supercontinuum generation, pulse guiding, generation of new frequencies, strong-field fiber optics including plasma generation, pulse compression etc. I develop and implement numerical methods and implement them for studies of various physical processes, ranging from discrete spatial diffraction through Kerr and Raman effects to photoionization.
Mechanism of line narrowing in continuous-wave-pumped fiber filled with Raman-active gas. Forward- and backward- propagating Stokes waves create a standing wave and a periodic lattice of population difference, which results in an array of deep subwavelength potential traps.
2. Linear and nonlinear nanooptics
Various nanometer-scaled systems are studied numerically, including metal-nanoparticle composites, photonic crystals, nanostructures, and rough surfaces. The considered optical processes include high harmonic generation, enhancement of nonlinearity, bistable optical behaviour, and focusing below the diffraction limit.
Bistable optical transmission in a planar nonlinear metal-dielectric array. A metal-like state B reflects incoming light; a dielectric-like state transmits light and has positive dielectric function due to nonlinearity.
3. Strong-field optics, high harmonic generation and material modification
Various phenomena occuring under the influence of photoionization are considered by the numerical methods are treated by home-made numerical algorithms developed to adress the corresponding problem. The investigated systems include high harmonic generation in gases, formation of overcritical plasma caused by light, nanoparticle-enhanced HHG and so on.
Dynamics of high-intensity, tightly focused light propagating through fused silica. The formation of overctirital plasma in the focal region introduces backreflection and strong perturbation to the field.
