Mid-infrared frequency comb via coherent dispersive wave generation in silicon nitride nanophotonic waveguides

Tobias Kippenberg, Hairun Guo, Camille Sophie Brès, Davide Grassani, Martin Hubert Peter Pfeiffer, Wenle Weng, Adrien Billat, Clemens Herkommer, Chuankun Zhang

Mid-infrared optical frequency combs are of significant interest for molecular spectroscopy due to the large absorption of molecular vibrational modes on the one hand, and the ability to implement superior comb-based spectroscopic modalities with increased ...

Observation of Second Harmonic and Sum Frequency in an Optically Poled Si3N4 Waveguide

Tobias Kippenberg, Camille Sophie Brès, Davide Grassani, Martin Hubert Peter Pfeiffer, Adrien Billat

Enhanced second order nonlinear processes in a Si3N4 waveguide following optically induced χ(2) is demonstrated, enabling the detection of a frequency doubled pulsed train and SFG with >-37 dB conversion efficiency for 18 W pump peak power. ...

Large second harmonic generation enhancement in Si3N4 waveguides by all-optically induced quasiphase- matching

Tobias Kippenberg, Camille Sophie Brès, Davide Grassani, Martin Hubert Peter Pfeiffer, Svyatoslav Kharitonov, Adrien Billat

Efficient second harmonic generation in integrated platforms is usually achieved by resonant structures, intermodal phase-matching or quasi-phase matching by periodically poling ferroelectric waveguides. However, in all these structures, it is impossible t ...
