  abstract     = {{We investigate the transient optical response in high-quality Cd0.88Zn0.12Te crystals in the regime of slow light propagation on the lower exciton-polariton branch. Femtosecond photoexcitation leads to very substantial transmission changes in a ∼10-meV broad spectral range within the transparency window of the unexcited semiconductor. These nonlinear optical signatures decay on picosecond time scales governed by carrier thermalization and recombination. The temporal and spectral dependence indicate the dynamical optical response as arising from excitation-induced dephasing and perturbed free induction decay. Model simulations for the optical response taking into account the actual exciton-polariton dispersion and excitation-induced dephasing of a nonlinearly driven two-level system support this interpretation.}},

  abstract     = {{We report about the fabrication and analysis of high Q photonic crystal cavities with metallic
Schottky-contacts. The structures are based on GaAs n-i membranes with an InGaAs quantum well
in the i-region and nanostructured low ohmic metal top-gates. They are designed for photocurrent
readout within the cavity and fast electric manipulations. The cavity structures are characterized by
photoluminescence and photocurrent spectroscopy under resonant excitation. We find strong cavity
resonances in the photocurrent spectra and surprisingly high Q-factors up to 6500. Temperature dependent
photocurrent measurements in the region between 4.5K and 310K show an exponential
enhancement of the photocurrent signal and an external quantum efficiency up to 0.26.}},
