State-of-the-Art and Future Directions in Optical Frequency Comb Sources, Enabling Technologies, and Applications

Optical frequency combs are powerful devices for realizing applications that rely on precision frequency synthesis, timing and metrology. This special topic covers developments in laser frequency comb sources, targeting wavelength regions beyond the standard telecommunication windows, compactness for large-scale deployment, and advances in subsystems and modules enabling enhanced performance or compatibility with system-level integration. Applications will be covered in atomic clock characterization, coherent communications, microwave synthesis, calibration of optical instrumentation, spectroscopy, as well as new emerging directions such as quantum information processing and biophotonics.
