“…The measurements of the spectral phase using stepped heterodyne [44] or generalized multi-heterodyne [45] techniques is an important step in the characterization of a multi-mode FP laser. If the mode phases are constant in time and if they follow a parabolic profile versus the mode pulsation, then it is possible to compensate the corresponding Group Delay Dispersion (GDD) using a standard single mode fiber of suitable length in order to obtain a pulse train at the output of the system [10], [13], [46].…”

In this paper we investigate with numerical simulations the rich multi-mode dynamics of Quantum Dot Fabry-Perot Lasers. We have used a Time Domain Traveling Wave approach including the electron and hole carrier dynamics in the various Quantum Dot confined states, the inhomogeneous broadening of the complex gain spectrum, the polarization dynamics and the effect of the carrier-photon interaction in the cavity. The role of the various non-linear interaction mechanism on the broadening of optical spectrum of the Quantum Dot laser has been investigated and the main parameters responsible for the phase locking between the longitudinal modes have been identified. We show that in some cases it is possible obtaining pulses after simulating the propagation of the laser output field in a dispersive medium. Many of the obtained simulation results are in good agreement with the experiments reported in the literature.

“…The ability to simultaneously record loss and dispersion has made dual-comb approaches attractive for characterizing telecom components, fiber gratings, and microresonators [78][79][80]. A modified dual-comb system can monitor active sources such as static and fast-swept cw waveforms [81][82][83][84], arbitrary optical waveforms [57,85,86], and even pulsed or incoherent sources [87,88]. All these techniques have the same underlying dual-comb/single-receiver architecture and serve to highlight the versatility of this approach, which is ultimately no more than a simple extension of standard heterodyne laser interferometry to frequency comb sources.…”

Dual-comb spectroscopy is an emerging new spectroscopic tool that exploits the frequency resolution, frequency accuracy, broad bandwidth, and brightness of frequency combs for ultrahigh-resolution, high-sensitivity broadband spectroscopy. By using two coherent frequency combs, dual-comb spectroscopy allows a sample's spectral response to be measured on a comb tooth-by-tooth basis rapidly and without the size constraints or instrument response limitations of conventional spectrometers. This review describes dual-comb spectroscopy and summarizes the current state of the art. As frequency comb technology progresses, dual-comb spectroscopy will continue to mature and could surpass conventional broadband spectroscopy for a wide range of laboratory and field applications.

“…Thanks to the versatility of our method to generate OFCs, the entire LO comb can be shifted by an amount δf with respect to the probe. In that case, the condition to avoid aliasing in detection becomes 32 , implying an increase by a factor M with respect to the usual condition required by conventional dual-comb spectroscopy 22 . As in the simple time-expansion mode, we control the spectral phase of the combs to ensure that a high average power is sent to the FUT.…”

Time-expanded phase-sensitive optical time-domain reflectometry

et al. 2021

Phase-sensitive optical time-domain reflectometry (ΦOTDR) is a well-established technique that provides spatio-temporal measurements of an environmental variable in real time. This unique capability is being leveraged in an ever-increasing number of applications, from energy transportation or civil security to seismology. To date, a wide number of different approaches have been implemented, providing a plethora of options in terms of performance (resolution, acquisition bandwidth, sensitivity or range). However, to achieve high spatial resolutions, detection bandwidths in the GHz range are typically required, substantially increasing the system cost and complexity. Here, we present a novel ΦOTDR approach that allows a customized time expansion of the received optical traces. Hence, the presented technique reaches cm-scale spatial resolutions over 1 km while requiring a remarkably low detection bandwidth in the MHz regime. This approach relies on the use of dual-comb spectrometry to interrogate the fibre and sample the backscattered light. Random phase-spectral coding is applied to the employed combs to maximize the signal-to-noise ratio of the sensing scheme. A comparison of the proposed method with alternative approaches aimed at similar operation features is provided, along with a thorough analysis of the new trade-offs. Our results demonstrate a radically novel high-resolution ΦOTDR scheme, which could promote new applications in metrology, borehole monitoring or aerospace.
