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 ...

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 ...

Backward Second-Harmonic Generation in Optically Poled Silicon Nitride Waveguides

Camille Sophie Brès, Jianqi Hu, Edgars Nitiss, Ozan Yakar

We report the inscription of quasi-phase-matching gratings in silicon nitride waveguides for backward second-harmonic-generation enabled by all-optical poling, therefore, circumventing the difficulties in inscribing poled domains with ultra-short periods. ...

Seeded Multimode Quasi-Phase-Matching in All-Optically Poled Silicon Nitride Waveguides

Camille Sophie Brès, Edgars Nitiss, Ozan Yakar

We demonstrate seeding-enabled all-optical poling of silicon nitride waveguides as short as 5 mm, and account for quasi-phase-matching (QPM) inside the waveguide between the fundamental mode of pump and higher order second-harmonic modes. ...
