Our group studies the nonlinear interaction between light and matter. Our research covers various areas of quantum and nonlinear optics from the single photon level to terawatts. Research areas includes ultrafast nonlinear optics, nanophotonics, nonlinear propagation in fibers and bulk media, the generation and processing of quantum light fields, and stimulated scattering processes.
A high power beam propagating in the medium can undergo a complex spatio-temporal evolution due to the interplay of dispersion, diffraction, and nonlinear effects such as self-focusing and ionization-induced refraction. We investigate experimentally the propagation dynamics in gases, bulk materials, and gas-filled hollow fibers at near-infrared and mid-infrared wavelengths, and we perform numerical simulations to predict or to explain novel phenomena.
Our research involves the investigation of photonics based approaches for optical computing and signal-processing. We are developing all-optical techniques for all-optical computing, random number generation, and ultrafast signal processing.
