Flexible terahertz opto-electronic frequency comb light source tunable over 3.5 THz
Dominik Theiner, Benedikt Limbacher, Michael Jaidl +2
We demonstrate a terahertz (THz) frequency comb that is flexible in terms of its frequency range and the number and spacing of comb lines. We use a combination of near-infrared las…
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,…
Analysis of silicon nitride partial Euler waveguide bends
Florian Vogelbacher, Stefan Nevlacsil, Martin Sagmeister +3
In this work we present a detailed analysis of individual loss mechanisms in silicon nitride partial Euler bends at a wavelength of 850 nm. This structure optimizes the transmissio…
Material Gain Concentration Quenching in Organic Dye-Doped Polymer Thin Films
Florian Vogelbacher, Xue Zhou, Jinhua Huang +5
The optimization of material gain in optically pumped dye-doped polymer thin films is an important task in the development of organic solid-state lasers. In this work, we present a…
Ultra-broadband quantum cascade laser operating from 1.88 to 3.82 THz
Markus Rösch, Mattias Beck, Martin J. Süess +4
We report on a heterogeneous active region design for terahertz quantum cascade laser based frequency combs. Dynamic range, spectral bandwidth as well as output power have been sig…
Spectrally resolved far-fields of terahertz quantum cascade lasers
Martin Brandstetter, Sebastian Schönhuber, Michael Krall +6
We demonstrate a convenient and fast method to measure the spectrally resolved far-fields of multimode terahertz quantum cascade lasers by combining a microbolometer focal plane ar…
