Picosecond Ultrasonics with Miniaturized Semiconductor Lasers
Michal Kobecki, Giuseppe Tandoi, Eugenio Di Gaetano +8
There is a great desire to extend ultrasonic techniques to the imaging and characterization of nanoobjects. This can be achieved by picosecond ultrasonics, where by using ultrafast…
Streak-camera measurements of single photons at telecom wavelength
Markus Allgaier, Vahid Ansari, Christof Eigner +8
Up to this point streak-cameras have been a powerful tool for temporal characterization of ultrafast light pulses even at the single photon level. However, the low signal-to-noise…
Picosecond control of quantum dot laser emission by coherent phonons
Thomas Czerniuk, Daniel Wigger, Andrey V. Akimov +5
A picosecond acoustic pulse can be used to control the lasing emission from semiconductor nanostructures by shifting their electronic transitions. When the active medium, here an e…
Systematic study of the influence of coherent phonon wave packets on the lasing properties of a quantum dot ensemble
D. Wigger, T. Czerniuk, D. E. Reiter +2
Coherent phonons can greatly vary light-matter interaction in semiconductor nanostructures placed inside an optical resonator on an ultrafast time scale. For an ensemble of quantum…
Nonlinear spectroscopy of exciton-polaritons in a GaAs-based microcavity
Johannes Schmutzler, Marc Aßmann, Thomas Czerniuk +4
We present a systematic investigation of two-photon excitation processes in a GaAs-based microcavity in the strong-coupling regime. We observe second harmonic generation resonant t…
Controlled lasing from active optomechanical resonators
T. Czerniuk, C. Brueggemann, J. Tepper +8
Planar microcavities with distributed Bragg reflectors (DBRs) host, besides confined optical modes, also mechanical resonances due to stop bands in the phonon dispersion relation o…
