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…
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…
Experimental realization of transverse mode conversion using optically induced transient long-period gratings
Tim Hellwig, Martin Schnack, Till Walbaum +2
We present the experimental realization of transverse mode conversion in an optical fiber via an optically induced long-period grating. The transient gratings are generated by femt…
Optically induced mode conversion in graded-index fibers using ultra-short laser pulses
Tim Hellwig, Till Walbaum, Carsten Fallnich
We propose the use of graded-index few-mode fibers for mode-conversion by long-period gratings (LPG) transiently written by ultrashort laser pulses using the optical Kerr effect. T…
