Year: 2025

Type: article

Abstract: Dual-Comb Spectroscopy In article number 2500062, Quanyong Lu and co-workers demonstrate compact self-detecting dual-comb spectroscopy based on dispersion-engineered, high-speed packaged QCLs under coherent injection locking. The high-speed design enables the QCL comb to serve as a high-bandwidth photodetector in the DCS system without the use of external detectors. Broad multiheterodyne signals and narrow dual-comb tooth are recorded from the self-detecting DCS system, which show the unique advantages in intermode coherence, spectral broadening, and system simplification.
