Quantum Cascade Surface Emitting Lasers
David Stark, Filippos Kapsalidis, Sergej Markmann +5
A low-cost single frequency laser emitting in the mid-infrared spectral region and dissipating minimal electrical power is a key ingredient for the next generation of portable gas…
Frequency chirped Fourier-Transform spectroscopy
Sergej Markmann, Martin Frankié, Mathieu Bertrand +6
Fast (sub-second) spectroscopy with high spectral resolution is of vital importance for revealing quantum chemistry kinetics of complex chemical and biological reactions. Fourier t…
An ultrastrongly coupled single THz meta-atom
Shima Rajabali, Sergej Markmann, Elsa Jöchl +5
Free-space coupling to strongly subwavelength individual optical elements is a central theme in quantum optics, as it allows to control and manipulate the properties of quantum sys…
THz intersubband electroluminescence from n-type Ge/SiGe quantum cascade structures
David Stark, Muhammad Mirza, Luca Persichetti +15
We report electroluminescence originating from L-valley transitions in n-type Ge/SiGe quantum cascade structures centered at 3.4 and 4.9 THz with a line broadenin…
