“…Since the early works demonstrating the OFC generation by GS of edge-emitting single mode lasers [1], an extensive application-driven research has been performed. The main targeted applications have been radio-over-fiber [2]- [4] and multi-carrier optical communications [5]- [7] but also applications such as dual comb spectroscopy have been pursued [8]. The effects of related key issues such as time jitter, phase noise/linewidth and modulation bandwidth, on the device performance in the targeted applications have been analysed [9]- [12].…”

A numerical model has been implemented and used for the simulation of the optical frequency combs generated by gain-switching single mode laser diodes, either free-running or subjected to optical injection. The dynamical model consists of three rate-equations including stochastic noise terms. An exhaustive comparison between the simulated and the experimental temporal profiles and optical spectra, generated in a wide range of switching and optical injection conditions has been performed. The range of the explored conditions leads to a variety of scenarios including actual combs and broad incoherent spectra, and frequencies in the range of, and well below, the relaxation oscillation frequencies. The detailed maps generated provide guidelines for selecting suitable operation conditions for specific comb characteristics. The excellent quantitative agreement found in the entire range of the explored operation conditions supports the validity of the model for the analysis of the comb generation mechanisms. The model has been used for ascertaining the role of the frequency chirp in the evolution of the comb spectra and discussing the physics underlying the effects of the optical injection.

“…However, in these phase modulation techniques the spectral bandwidth of the FC is ultimately limited by the bandwidth of the function generator (a few tens of GHz). Another approach that has been proposed to produce FCs from a CW laser combines gain-switching and optical injection locking in a semiconductor laser [32,33]. This method makes it possible to achieve dual-comb generation (potentially from visible to mid-infrared), although the spectra thus obtained are still limited to tens of lines.…”

We propose and characterize experimentally a new source of optical frequency combs for performing multi-heterodyne spectrometry. This comb modality is based on a frequency-shifting loop seeded with a continuous-wave (CW) monochromatic laser. The comb lines are generated by successive passes of the CW laser through an acousto-optic frequency shifter. We report the generation of frequency combs with more than 1500 mutually coherent lines, without resorting to non-linear broadening phenomena or external electronic modulation. The comb line spacing is easily reconfigurable from tens of MHz down to the kHz region. We first use a single acousto-optic frequency comb to conduct self-heterodyne interferometry with a high frequency resolution (500 kHz). By increasing the line spacing to 80 MHz, we demonstrate molecular spectroscopy on the sub-millisecond time scale. In order to reduce the detection bandwidth, we subsequently implement an acousto-optic dual-comb spectrometer with the aid of two mutually coherent frequency shifting loops. In each architecture, the potentiality of acousto-optic frequency combs for spectroscopy is validated by spectral measurements of hydrogen cyanide in the near-infrared region.

“…Gain-switching (GS) has proven its convenience as a method for generating OFCs due to its easy implementation, robustness and stability, controllable repetition rate, and adaptability for integration using generic platforms [4][5][6]. OFCs generated by GS have found applications mainly in optical communications [1,7] but also in sub-terahertz generation [8] and more recently in absorption spectroscopy [9,10]. The usual implementation of the GS technique for the generation of OFCs consists in driving the laser with the superposition of a direct bias current and a radio-frequency (RF) sinusoidal current.…”

“…And yet, it is in this low repetition frequency range where OFCs generated by GS have recently found interesting advantages in dual-comb optical spectroscopy [9]. These advantages are simplicity of use, control of the line spacing, compactness and potential for integration, and capabilities for implementation outside the 1.5 µm spectral range.…”

“…Obviously, these advantages can only be fully exploited if the number of spectral lines of the OFC and the separation between them can sustain the high resolution in a sufficiently broad spectral range which is characteristic of dual-comb spectroscopy. The authors in [9] illustrate the potential of their approach with the OFC generated by a 1 GHz sinusoidal RF current. In order to get a comb with enough number of lines, they had to make a meticulous optimization of the switching and optical injection conditions.…”

Enhanced optical frequency comb generation by pulsed gain-switching of optically injected semiconductor lasers

We report on the experimental generation of broad and flat optical frequency combs (OFC) in a 1550 nm laser diode using gain switching with pulsed electrical excitation together with optical injection. The combination of both techniques allows the generation of high-quality OFCs at a repetition frequency of 500 MHz, showing a low-noise optical spectrum with unprecedent features in terms of width (108 tones within 10 dB) and flatness (56 tones within 3 dB) in comparison with those previously reported for this modulation frequency. The influence of the injection conditions on the OFC quality is studied. Using these two techniques, it has been possible to reduce the separation between tones, generating high spectral performance OFCs with a repetition rate of 100 MHz.
