Mid-Infrared Ring Interband Cascade Laser: Operation at the Standard Quantum Limit
Georg Marschick, Jacopo Pelini, Tecla Gabbrielli +9
Many precision applications in the mid-infrared spectral range have strong constraints based on quantum effects that are expressed in particular noise characteristics. They limit,…
Intensity correlations in quantum cascade laser harmonic frequency combs
Tecla Gabbrielli, Natalia Bruno, Nicola Corrias +10
A novel study on harmonic frequency combs emitted by Quantum Cascade Lasers (QCLs) is here presented, demonstrating the presence of intensity correlations between twin modes charac…
Modulation Instability Induced Frequency Comb Generation in a Continuously Pumped Optical Parametric Oscillator
S. Mosca, M. Parisi, I. Ricciardi +7
Continuously pumped passive nonlinear cavities can be harnessed for the creation of novel optical frequency combs. While most research has focused on third-order "Kerr" nonlinear i…
Fundamental thermal noise in droplet microresonators
Antonio Giorgini, Saverio Avino, Pietro Malara +2
Liquid droplet whispering-gallery-mode microresonators open a new research frontier for optomechanics and photonic devices. At visible wavelengths, where most liquids are transpare…
Direct generation of optical frequency combs in nonlinear cavities
S. Mosca, I. Ricciardi, M. Parisi +4
Quadratic nonlinear processes are currently exploited for frequency comb transfer and extension from the visible and near infrared regions to other spectral ranges where direct com…
Sub-kHz linewidth narrowing of a mid-infrared OPO idler frequency by direct cavity stabilization
I. Ricciardi, S. Mosca, M. Parisi +4
We stabilize the idler frequency of a singly-resonant optical parametric oscillator directly to the resonance of a mid-infrared Fabry-Pérot reference cavity. This is accomplished b…
Frequency comb generation in quadratic nonlinear media
Iolanda Ricciardi, Simona Mosca, Maria Parisi +4
We experimentally demonstrate and theoretically explain the onset of optical frequency combs in a simple cavity-enhanced second-harmonic-generation system, exploiting second-order…
Enhanced sensing with quasi-degenerate mode in fiber Bragg gratings ring cavities
C. E. Campanella, A. Giorgini, S. Avino +4
In this paper, we report the model and the experimental demonstration of a new optical resonator formed by inserting a Fiber Bragg Grating (FBG) in a closed fiber loop. The spectra…
Observing the intrinsic linewidth of a quantum-cascade laser: beyond the Schawlow-Townes limit
S. Bartalini, S. Borri, P. Cancio +6
A comprehensive investigation of the frequency-noise spectral density of a free-running mid-infrared quantum-cascade laser is presented for the first time. It provides direct evide…
Saturated-absorption cavity ring-down spectroscopy
G. Giusfredi, S. Bartalini, S. Borri +4
We report on a novel approach to cavity-ring-down spectroscopy with the sample gas in saturated-absorption regime. This technique allows to decouple and simultaneously retrieve emp…
