Photon-driven broadband emission and RF injection locking of THz quantum cascade laser frequency combs
Andres Forrer, Martin Franckié, David Stark +4
We present homogeneous quantum cascade lasers (QCLs) emitting around 3 THz which display bandwidths up to 950 GHz with a single stable beatnote. Devices are spontaneously operating…
Gain dynamics in a heterogeneous terahertz quantum cascade laser
C. G. Derntl, G. Scalari, D. Bachmann +4
The gain recovery time of a heterogeneous active region terahertz quantum cascade laser is studied by terahertz-pump,i terahertz-probe spectroscopy. The investigated active region,…
Thermoelectrically cooled THz quantum cascade laser operating up to 210 K
Lorenzo Bosco, Martin Franckié, Giacomo Scalari +3
We present a \MF{terahertz} quantum cascade laser operating on a thermoelectric cooler up to a record-high temperature of 210.5 K. The active region design is based on only two qua…
Superradiantly limited linewidth in complementary THz metamaterials on Si-membranes
Janine Keller, Johannes Haase, Felice Appugliese +6
We study complementary double split ring THz resonators fabricated on a 10 mum thin Si-membrane. The linewidths of the fundamental LC-mode and dipolar mode are drastically narrowin…
On-chip mid-infrared and THz frequency combs for spectroscopy
Giacomo Scalari, Jérôme Faist, Nathalie Picqué
Frequency combs have revolutionized time and frequency metrology and in recent years, new frequency comb lasers that are highly compact or even on-chip have been demonstrated in th…
Pulses from a mid-infrared quantum cascade laser frequency comb using an external compressor
Matthew Singleton, Mattias Beck, Jerome Faist
A Martinez-type stretcher-compressor is used to modify the spectral phases of a high-power (~1 W) QCL comb emitted at 8.2 μm with more than 100 cm-1 spectral bandwidth. Using this…
