Metasurface-Enhanced Mid-Infrared Imaging Spectroscopy with Broadband Quantum Cascade Lasers
Ivan Sinev, Alessio Cargioli, Diego Piciocchi +3
Mid-infrared (mid-IR) spectroscopy offers unparalleled opportunities in sensing through chemically specific detection of molecular absorption fingerprints. Yet, its practical appli…
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…
Spectral shaping of fast-gain frequency combs through phases in synthetic dimensions
Diego Piciocchi, Alexander Dikopoltsev, Ina Heckelmann +3
Optical frequency comb devices have unlocked new capabilities in telecommunications, sensing, and metrology. Yet, precise in situ control of the comb spectral envelope remains extr…
Quantum Cascade Lasers as Broadband Sources via Strong RF Modulation
Alessio Cargioli, Diego Piciocchi, Mathieu Bertrand +5
In this work, we demonstrate that in a regime of strong modulation, by generating pulses of the length of the order of a few cavity lifetimes (hundreds of ps), a broadband quantum…
The infinity-loop microresonator: A new integrated photonic structure working on an exceptional surface
Riccardo Franchi, Stefano Biasi, Diego Piciocchi +1
Exceptional points, where eigenvalues and eigenvectors coalesce, impact the behavior of different photonics components that show, e.g., enhanced sensing, coherent perfect absorptio…
