Ultrafast exciton transfers in DNA and its nonlinear optical spectroscopy.
We have calculated the nonlinear response function of a DNA duplex helix including the contributions from the exciton population and coherence transfers by developing an appropriate exciton theory as well as by utilizing a projector operator technique. As a representative example of DNA double helices, the B-form (dA)10-(dT)10 is considered in detail. The Green functions of the exciton populati...
متن کاملNonlinear Black Phosphorus for Ultrafast Optical Switching
The outstanding electronic and optical properties of black phosphorus (BP) in a two-dimensional (2D) but unique single-layer puckered structure have opened intense research interest ranging from fundamental physics to nanoscale applications covering the electronic and optical domains. The direct and controllable electronic bandgap facilitating wide range of tunable optical response coupled with...
متن کاملUltrafast Nonlinear Spectroscopy of Hybrid Plasmonic Systems
In this thesis, the nonlinear optical properties as well as the ultrafast temporal dynamics of hybrid plasmonic systems are studied. The model system under investigation simultaneously provides localized plasmonic modes in a metallic nanowire grating and photonic modes in an adjacent dielectric waveguide slab. The coupling of the modes leads to the formation of polaritonic eigenstates and signi...
متن کاملIntegrated Ultrafast Nonlinear Optical Devices in Silicon
Silicon-on-insulator (SOI) provides an intriguing system for developing massively integrated optics. By leveraging the processes and systems developed for electronics fabrication, it is possible to make highly repeatable devices where complexity can be scaled up through the use of wafer-scale batch fabrication. Because the mode concentration in silicon waveguides is two orders of magnitude high...
متن کاملUltrafast nonlinear optical studies of silicon nanowaveguides.
Results of a self-consistent ultrafast study of nonlinear optical properties of silicon nanowaveguides using heterodyne pump-probe technique are reported. The two-photon absorption coefficient and free-carrier absorption effective cross-section were determined to be 0.68cm/GW, and 1.9x10(-17) cm2, respectively and the Kerr coefficient and free-carrier-induced refractive index change 0.32x10(-13...
