Silicon nitride electric-field poled microresonator modulator
Camille Sophie Brès, Anton Stroganov, Boris Zabelich, Christian André Clément Lafforgue, Edgars Nitiss
Stoichiometric silicon nitride is a highly regarded platform for its favorable attributes, such as low propagation loss and compatibility with complementary metal-oxide-semiconductor technology, making it a prominent choice for various linear and nonlinear ...
2024Wavelength-stabilized figure-of-9 thulium-doped all-fiber laser emitting 560 fs pulses
Camille Sophie Brès, Moritz Bartnick, Gayathri Bharathan
We demonstrate a figure-of-9 all-fiber thulium-doped laser (TDFL) that generates 560 fs long pulses at 1948 nm wavelength. In order to achieve self-starting passive mode-locking, we utilize an in-fiber Faraday rotator to induce a nonreciprocal phase shift. ...

Chip -scale optical frequency combs enable the generation of highly -coherent pulsed light at gigahertz-level repetition rates, with potential technological impact ranging from telecommunications to sensing and spectroscopy. In combination with techniques ...
Optica Publishing Group2024Tunable photo-induced second-harmonic generation in a mode-engineered silicon nitride microresonator
Camille Sophie Brès, Jianqi Hu, Anton Stroganov, Boris Zabelich, Edgars Nitiss
All-optical poling enables reconfigurable and efficient quasi-phase-matching for second-order parametric frequency conversion in silicon nitride integrated photonics. Here, we report broadly tunable milliwatt-level second-harmonic generation in a small fre ...
Optica Publishing Group2023Cost-effective equalization of electro-optic frequency combs in a Sagnac interferometer
Camille Sophie Brès, Jianqi Hu, Ivan Cardea
We present a cost-effective electro-optic frequency comb generation and equalization method using a single phase modulator inserted in a Sagnac interferometer layout. The equalization relies on the interference of comb lines generated in both clockwise and ...
Optica Publishing Group2023Single-shot Kramers-Kronig complex orbital angular momentum spectrum retrieval
Camille Sophie Brès, Jianqi Hu, Yujie Chen
Orbital angular momentum (OAM) spectrum diagnosis is a fundamental building block for diverse OAM-based systems. Among others, the simple on-axis interferometric measurement can retrieve the amplitude and phase information of complex OAM spectra in a few s ...

Tobias Kippenberg, Camille Sophie Brès, Marco Clementi, Junqiu Liu, Edgars Nitiss
Second-harmonic generation allows for coherently bridging distant regions of the optical spectrum, with applications ranging from laser technology to self-referencing of frequency combs. However, accessing the nonlinear response of a medium typically requi ...
2023Self-injection Locked Second-Harmonic Generation in Optically Poled Silicon Nitride Microresonators
Tobias Kippenberg, Camille Sophie Brès, Marco Clementi, Junqiu Liu, Edgars Nitiss
We present a narrow-linewidth second-harmonic source based on a laser diode injection locked to an optically poled silicon nitride microresonator. The device is a compact, highly-coherent dual-wavelength source, with high conversion efficiency up to 280%/W ...
