Summary: High-performance hyperspectral imaging is in high demand due to its wide range of capabilities. However, traditional systems have limitations in resolving narrow spectral features. In this study, we introduce the first hyperspectral dual-comb imaging system with sub-GHz optical resolutions and fast acquisition rates in the mid-infrared region.

Summary: In holography, using a large number of narrow laser lines at precisely defined optical frequencies simultaneously can enhance the capabilities of digital holography. This advancement, known as dual-comb holography, allows for novel optical diagnostics such as high spectral resolving power in three-dimensional imaging and precise dimensional metrology over large distances without interferometric phase ambiguity.

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: Open-path dual-comb spectroscopy has been extended to the mid-infrared 5 µm atmospheric window, enabling high precision measurements of multispecies atmospheric gas concentrations, including primary greenhouse gases and criteria air pollutants. The retrieved ratios of excess CO versus CO2 and N2O versus CO2 show variations and discrepancies with previous studies and emission inventories.

Summary: This paper introduces a novel mid-infrared compressive hyperspectral imaging system that combines an improved MIR-DMD with an off-the-shelf infrared spectroradiometer to capture hyperspectral images in the mid-infrared spectral range. The development of a dual-stage image reconstruction method and the use of measurement without coding as side information has improved the quality of reconstruction for infrared hyperspectral images. This system represents a less expensive alternative to conventional mid-infrared hyperspectral imaging systems.

Summary: The authors present a microcomb-based dual-comb spectroscopy sensor with GHz resolution for mid-infrared gas sensing. The system stability is determined by a single high-Q microresonator, making it simplified and eliminating the need for external frequency locking. The methane and ethane spectra can be measured over short intervals as 0.5 ms, showing potential for chip-based architectures in mid-IR gas sensors for various applications.

Summary: To meet the challenges of high-resolution molecular spectroscopy, increasingly sophisticated spectroscopic techniques were developed. The recent development of dual-comb spectroscopy at high-resolution makes this technique a powerful tool for gas phase studies. This study reports on the use and characterization of the IRis-F1, a tabletop mid-infrared dual-comb spectrometer, in the newly developed step-sweep mode.

Summary: In this study, a wide-field hyperspectral mid-infrared microscope based on multidimensional single-pixel imaging was demonstrated. The microscope utilized a high brightness MIR supercontinuum source for sample illumination and a single micro-opto-electro-mechanical digital micromirror device (DMD) for spatial and spectral differentiation. The DMD served the purpose of masking captured scenes and dispersing the projected field for wavelength selection without additional optical elements. The microscope's imaging and spectral capabilities were characterized, achieving high spatial and spectral resolutions. Label-free chemical imaging and examination of polymer compounds and red blood cells were successfully demonstrated. The design showed improved sample throughput in MIR chemical and biomedical imaging with tunable field of view and adjustable spatial resolution.

Summary: Optomechanical interactions enable coherent interconversion of signals between optical and mechanical domains. Extreme light-matter coupling at nanoscale mode volumes allows single mid-infrared (MIR) photon sensitivity. This study demonstrates frequency upconversion by utilizing infrared absorption and Raman activity of molecular vibrations in plasmonic nanocavities, showing potential for low-cost and large-scale infrared detectors and spectroscopic techniques.

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.
