Multi-color stimulated Raman scattering with a frame-to-frame wavelength-tunable fiber-based light source
Thomas Würthwein, Kristin Wallmeier, Maximilian Brinkmann +4
We present multi-color imaging by stimulated Raman scattering (SRS) enabled by an ultrafast fiber-based light source with integrated amplitude modulation and frame-to-frame wavelen…
High-sensitivity frequency modulation CARS with a compact and fast tunable fiber-based light source
Thomas Würthwein, Maximilian Brinkmann, Tim Hellwig +2
Frequency modulation coherent anti-Stokes Raman scattering (FM CARS) is presented, using a compact as well as fast and widely tunable fiber-based light source. With this light sour…
A hybrid-integrated diode laser in the visible spectral range
Cornelis A. A. Franken, Albert van Rees, Lisa V. Winkler +7
Generating visible light with wide tunability and high coherence based on photonic integrated circuits is of high interest for applications in biophotonics, precision metrology and…
Hybrid integrated semiconductor lasers with silicon nitride feedback circuits
Klaus-J. Boller, Albert van Rees, Youwen Fan +17
Hybrid integrated semiconductor laser sources offering extremely narrow spectral linewidth as well as compatibility for embedding into integrated photonic circuits are of high impo…
Supercontinuum generation in media with sign-alternated dispersion
Haider Zia, Niklas M. Lüpken, Tim Hellwig +2
When an ultrafast optical pulse with high intensity is propagating through transparent material a supercontinuum can be coherently generated by self-phase modulation, which is esse…
Ultrafast, low-power, all-optical switching via birefringent phase-matched transverse mode conversion in integrated waveguides
Tim Hellwig, Jörn P. Epping, Martin Schnack +2
We demonstrate the potential of birefringence-based, all-optical, ultrafast conversion between the transverse modes in integrated optical waveguides by modelling the conversion pro…
