Ultrafast wavelength-tunable optical measurements on semiconductor nanowires allow us to independently probe the dynamics of electrons, holes, and defect states. These investigations reveal the influence of two-dimensional confinement on carrier dynamics in these nanosystems.

We demonstrate reconfigurable microfluidic photonic crystal double-heterostructure cavities by local fluid infiltration of select air holes. Properties of the microfluidic cavities are experimentally studied by evanescent coupling and analyzed by numerical simulations.

Single and multiple holes in optically thick gold layers are investigated with cathodoluminescence to obtain optical information beyond the diffraction limit. Excitation patterns and spectral shapes are observed to shift when the hole shape is varied. It is shown that the specific relative orientation of dimers and trimers of holes leads to shifts in the spectrum and changes of the excitation patterns.
