Autor: Anton Stroganov, Edgars Nitiss, Camille-Sophie Brès, Ozan Yakar

Publikováno v: Optics Letters

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–s

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

Autor: Edgars Nitiss, Tobias J. Kippenberg, Ozan Yakar, Boris Zabelich, Junqiu Liu, Rui Ning Wang, Camille-Sophie Brès

Publikováno v: Photonics Research

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

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 per

Seeded multimode quasi-phase-matching in all-optically poled silicon nitride waveguides

Autor: Camille-Sophie Brès, Edgars Nitiss, Ozan Yakar

Conference on Lasers and Electro-Optics

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.
