Summary: Frequency-modulated continuous wave (FMCW) light detection and ranging (lidar) is a promising solution for three-dimensional (3D) imaging and autonomous driving. The use of a cascaded modulator electro-optic (EO) frequency comb in FMCW lidar enables massively parallel ranging with a high range resolution of 1-cm. The achieved measurement rate of over 12 megapixels per second proves its feasibility and potential applications in fields where high range resolution is required, such as criminal investigation and precision machining.

Summary: This article presents a theoretical, numerical and experimental assessment of the impact of speckle on a dual electro-optic frequency comb (EOFC) based system for integrated path differential absorption (IPDA) measurements. The study found that the speckle-related error in the concentration estimate is an increasing function of the product between the roughness of the backscattering surface and the EOFC line-spacing. It also demonstrates that decorrelation of speckle noise can be advantageously exploited for surface characterization in a dual EOFC configuration.

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.

Summary: A chirped-pulse interleaving method using electro-optic phase modulators (EOM) to generate dual optical frequency combs in a free-running all-fiber system is reported. This method allows for easy modification of the linear scan rate and comb resolution by over three orders of magnitude, and significantly increases the spectral bandwidth coverage. These techniques are suitable for applications in remote sensing of greenhouse gas emissions, molecular reaction dynamics, and sub-Doppler studies across wide spectral regions accessible to EOMs.

Summary: Developments in integrated photonics have led to the emergence of stable, compact and broadband comb generators. The integrated electro-optic frequency comb presented in this research demonstrates a high conversion efficiency and a wide optical span, and can serve as an on-chip femtosecond pulse source. It also enables the simultaneous effects of electro-optic and third-order nonlinearity, paving the way for practical optical frequency comb generators and exploring new regimes of optical physics.

Summary: We have achieved precise photonic thermometry using dual-comb spectroscopy and a phase-shifted fiber Bragg grating. Our measurements demonstrate a readout stability of 7.5 mK at 1 second and the ability to detect temperature changes of similar magnitude, making it suitable for industrial applications. Our dual-comb approach allows for rapid sensing of dynamic temperatures, and our scalable electro-optic generation scheme enables broad sensing range without the need for laser tuning. Our demonstration paves the way for a universal interrogator that can be deployed to multiple photonic devices in parallel, potentially unlocking complex multi-physical quantity measurements.

Summary: We present an architecture for wavelength-division-multiplexed coherent data center links using resonator-enhanced electro-optic frequency comb generators. The phase noise in each frequency comb is determined by the optical phase noise of the seed laser and the phase noise of the microwave oscillator. We propose an analog coherent receiver that performs carrier recovery on all wavelength channels using only two phase-locked loops.
