Broadband quasi-phase-matching in dispersion-engineered all-optically poled silicon nitride waveguides

Rui Ning Wang, Tobias Kippenberg, Camille Sophie Brès, Junqiu Liu, Edgars Nitiss, Ozan Yakar, Boris Zabelich

Quasi-phase-matching (QPM) has become one of the most common approaches for increasing the efficiency of nonlinear three-wave mixing processes in integrated photonic circuits. Here, we provide a study of dispersion engineering of QPM second-harmonic (SH) g ...

Formation Rules and Dynamics of Photoinduced χ(2) Gratings in Silicon Nitride Waveguides

Tobias Kippenberg, Martin Hubert Peter Pfeiffer, Camille Sophie Brès, Davide Grassani, Edgars Nitiss, Tianyi Liu

Silicon nitride has emerged as a prominent platform for building photonics integrated circuits. While its nonlinear properties based on third-order effects have been successfully exploited, an efficient second harmonic generation in standard stoichiometric ...

Broadband Quasi-Phase-Matching in All-Optically Poled Stoichiometric Silicon Nitride Waveguides

Camille Sophie Brès, Edgars Nitiss, Boris Zabelich

We show how broadband (>30nm) quasi-phase matching in all-optically poled Si3N4 waveguides provides a platform for efficient sum-frequency generation, and for femtosecond pulse processing such as fcEo detection without the need for group velocity engineeri ...

Highly tunable second-harmonic generation in all-optically poled silicon nitride waveguides

Camille Sophie Brès, Anton Stroganov, Edgars Nitiss, Ozan Yakar

The availability of nonlinear parametric processes, such as frequency conversion in photonic integrated circuits is essential. In this contribution, we demonstrate a highly tunable second-harmonic generation in a fully complementary metal–oxide–semiconduct ...

Optically Probed Time Dynamics of χ(2) Grating Inscription in SiN Waveguides

Tobias Kippenberg, Camille Sophie Brès, Davide Grassani, Edgars Nitiss, Tianyi Liu

Silicon Nitride (S13N4) waveguide platforms have seen significant interest in the recent years, motivated by several advantageous properties such as compatibility with CMOS fabrication standards, low propagation loss, high refractive index and optical nonl ...
