Free-Running Ring Quantum Cascade Laser with 50 kHz Linewidth
Alexandre Parriaux, Ina Heckelmann, Mathieu Bertrand +3
We report on the noise characterization of a free-running ring quantum cascade laser resonator emitting a single frequency mode around 7.7 m. Using a gas cell filled with N…
Time-resolved spectroscopy of noise-driven collective states of light
Diego Piciocchi, Ina Heckelmann, Alexander Dikopoltsev +6
We study a collective liquid state of light in a fast-gain laser. Controlled temporal noise on the cavity modulation creates a fluctuating linear potential along the synthetic freq…
On-chip pulse generation at 8 μm wavelength
Annabelle Bricout, Mathieu Bertrand, Philipp Täschler +15
The mid-infrared spectral region holds growing importance for applications such as gas sensing and spectroscopy. Although compact ultrashort pulse laser sources are essential to en…
Integrated thin film lithium niobate mid-infrared modulator
Pierre Didier, Prakhar Jain, Mathieu Bertrand +7
The mid-infrared spectral range holds great promise for applications such as molecular spectroscopy and telecommunications. Many key molecules exhibit strong absorption features in…
Non-resonant Optical Injection Locking in Quantum Cascade Laser Frequency Combs
Alexandre Parriaux, Kenichi N. Komagata, Mathieu Bertrand +4
Optical injection locking of the repetition frequency of a quantum cascade laser frequency comb is demonstrated using an intensity modulated near-infrared light at 1.55 m illum…
