Nuisance blue-green algal blooms contribute to aesthetic degradation of water resources and produce toxins that can have serious adverse human health effects. Current field-based methods for detecting...
Competition between electronic Kerr and free carrier effects in an ultimate-fast optically switched semiconductor microcavity
electronic Kerr free carrier effects semiconductor microcavity Optics
2012/5/17
We have performed ultrafast pump-probe experiments on a GaAs-AlAs microcavity with a resonance near 1300 nm in the "original" telecom band. We concentrate on ultimate-fast optical switching of the cav...

We report on a simple and robust technique to generate a dispersive signal which serves as an error signal to electronically stabilize a monomode cw laser emitting around an atomic resonance. We explo...
The complete census of optically selected AGNs in the Coma Supercluster: the dependence of AGN activity on the local environment
Galaxies: clusters: individual: Coma Galaxies evolution Galaxies nuclei
2011/10/11
To investigate the dependence of the occurrence of active galactic nuclei (AGNs) on local galaxy density, we study the nuclear properties of ~5000 galaxies in the Coma Supercluster whose density spans...
