Ultrafast magneto-optical spectroscopy of (III,manganese)V ferromagnetic semiconductors
This thesis describes magneto-optical processes in ferromagnetic (III,Mn)V semiconductors and their heterostructures induced by femtosecond laser pulses. Two-color ultrafast magneto-optical spectroscopy has been developed, ...
Multiple scattering of broadband terahertz pulses
Propagation of single-cycle terahertz (THz) pulses through a random medium leads to dramatic amplitude and phase variations of the electric field because of multiple scattering. We present the first set of experiments that ...
Subradiant, superradiant and Fano resonances in dimer and ring/disk nanocavities
Subradiant and superradiant plasmon modes in ring/disk nanocavities and dialers are investigated theoretically and experimentally. The subradiance is obtained through an overall reduction of the total dipole moment of the ...
Novel symmetric and asymmetric plasmonic nanostructures
Metal-dielectric nanostructures capable of supporting electromagnetic resonances at optical frequencies are the vital component of the emerging technology called plasmonics. Plasmon is the electromagnetic wave confined at ...
Acousto-optic multiphoton laser scanning microscopy and multiphoton photon counting spectroscopy: Applications and implications for optical neurobiology
Multiphoton excitation of molecular probes has become an important tool in experimental neurobiology owing to the intrinsic optical sectioning and low light scattering it affords. Using molecular functional indicators, ...
