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…
