TOP Research Themes & Directions

The TOP research lies at a crossroads of nonlinear photonics, statistical optics, and plasmonics. First, we explore the formation, propagation, and control of self-similar optical pulses, fields and plasmons in fibers, dielectric waveguides, and plasmonic nano structures, respectively. Second, we examine nonlinear optical effects in plasmonics with potential applications to nonlinear imaging and spectroscopy. We also research gas nonlinear optical effects in hollow-core photonic crystal fibers, including linear and nonlinear resonant pulse propagation and stimulated Raman scattering. Further, we investigate propagation, interaction, and shaping of ultrashort statistical pulses in fibers and semiconductor quantum dot media as well as optical fields in plasmonic nano structures with potential applications to high-precision optical communications, information transfer, and optical computing. Finally, we examine fine-scale correlations of statistical fields in the vicinity of regions where the fields are completely incoherent within the framework of statistical singular optics.
