Summary: Dual-comb microscopy (DCM) is an imaging modality based on optical-frequency-comb (OFC) mode, providing scan-less full-field imaging and confocal amplitude and phase imaging. The practicality of DCM is limited by the complexity and costs of fully frequency-stabilized OFC sources. This study introduces a low-complexity OFC source for DCM using a bidirectional single-cavity dual-comb fiber laser (SCDCFL), and demonstrates the effectiveness of computational image correction in reducing image blur. The proposed method enhances DCM generality and practicality, suggesting a possibility to extend computational image correction to dynamic objects.

Summary: Photoacoustic spectroscopy (PAS) using two optical combs offers broad bandwidths, high resolutions, fast acquisition speeds, and wavelength-independent detection. However, sensitivity and specificity are limited. In this study, we demonstrate comb-enabled PAS with enhanced sensitivity and nonlinear spectral hole-burning defined resolution, enabling trace detection and Doppler-free gas sensing.

Summary: This article reports on an ultra-sensitive and broadband mid-infrared upconversion spectrometer that utilizes a silicon nitride nanophotonic waveguide to create a supercontinuum source covering 1.5-4.2 µm. High-efficiency and low-noise nonlinear frequency upconversion is achieved using coincidence pulsed pumping and spectro-temporal optimization, enabling silicon detectors to perform MIR single-photon spectroscopy at 0.2 photons/nm/pulse. Furthermore, the upconversion-based array spectrometer achieves high-speed spectral acquisition rates beyond 200 kHz, which is about tenfold faster than state-of-the-art FTIR-based spectrometers at a comparable spectral resolution. The achieved features of broadband spectral coverage, single-photon sensitivity, and sub-MHz refreshing rate open up new possibilities for infrared transient spectral measurements in combustion analysis, high-throughput sorting, and reaction tracking, among others.

Summary: Mid-infrared (MIR) spectrometers are essential for studying molecular fingerprinting and hyper-spectral imaging. However, current GHz MIR dual-comb absorption spectrometers lack the ability to combine high speed, high spectral resolution, and broad optical bandwidth. This study introduces a broadband MIR frequency comb laser platform that overcomes these limitations, enabling accurate characterization of complex, transient events in chemistry, combustion, and microscopy.

Summary: In this study, a sandwich-integrated all-ChG microresonator was used to demonstrate a mid-infrared (MIR) microcomb generator covering a wavelength range from 6.94μm to 12.04μm. The novel microresonator features a symmetrically uniform distribution of the mode field, precise dispersion engineering, and low optical loss, offering a wide transmission window, high Kerr nonlinearity, and hybrid-fabrication flexibility on a silicon wafer. Numerical simulations successfully demonstrated a MIR Kerr frequency comb with a bandwidth of 5.1μm, assisted by dispersive waves. A feasible fabrication scheme for on-demand ChG microresonators was also proposed. These findings highlight the advantages of integrated ChG photonic devices in MIR nonlinear photonics and their potential applications in MIR spectroscopy.

Summary: Laser frequency comb generators on photonic chips show the potential for integrated dual-comb microspectrometers. Among nanophotonic platforms, the low-loss thin-film lithium-niobate-on-insulator technology stands out with its ability to combine various optoelectronic and nonlinear optical functionalities. In this study, a critical step towards on-chip fabrication of a fully functional instrument is demonstrated with an electro-optic microring-based dual-comb interferometer. The system achieves spectra with a range of 1.6 THz and a resolution of 10 GHz in a single measurement without the need for frequency scanning or moving parts. The frequency agility of the system enables multiplexed sensing of non-adjacent spectral regions without compromising the signal-to-noise ratio. These findings highlight the promising potential of electro-optic-based nanophotonic technology for broad-spectral-bandwidth molecular sensing.
