Multi-channel swept source optical coherence tomography concept based on photonic integrated circuits
Stefan Nevlacsil, Paul Muellner, Alejandro Maese-Novo +7
In this paper, we present a novel concept for a multi-channel swept source optical coherence tomography (OCT) system based on photonic integrated circuits (PICs). At the core of th…
Broadband low loss and ultra-low crosstalk waveguide crossings based on multimode interferometer for 840 nm operation
Stefan Nevlacsil, Paul Muellner, Martin Sagmeister +2
Broadband low loss and ultra-low crosstalk waveguide crossings are a crucial component for photonic integrated circuits to allow a higher integration density of functional componen…
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…
Broadband SiN asymmetric directional coupler for 840 nm operation
Stefan Nevlacsil, Moritz Eggeling, Paul Muellner +4
Silicon nitride based photonic integrated circuits offer a wavelength operation window in the near infrared down to visible light, which makes them attractive for life science appl…
