Femtosecond-scale switching based on excited free-carriers
Y. Sivan, G. Ctistis, E. Yuce +1
We describe novel optical switching schemes operating at femtosecond time scales by employing free carrier (FC) excitation. Such unprecedented switching times are made possible by…

Extraction of optical Bloch modes in a photonic-crystal waveguide
S. R. Huisman, G. Ctistis, S. Stobbe +4
We perform phase-sensitive near-field scanning optical microscopy on photonic-crystal waveguides. The observed intricate field patterns are analyzed by spatial Fourier transformati…

Controlling the quality factor of a tuning-fork resonance between 9 K and 300 K for scanning-probe microscopy
Georgios Ctistis, Eric Frater, Simon R. Huisman +4
We study the dynamic response of a mechanical quartz tuning fork in the temperature range from 9 K to 300 K. Since the quality factor Q of the resonance strongly depends on tempera…
