Real-time Optical Monitoring of Telecom Data Signals Utilizing Dispersive Fourier Transformation

We propose a real-time optical monitoring (RTOM) system for dynamic spectral analysis of wavelength-division-multiplexed (WDM) telecommunication data streams over broad frequency bands (e.g., full C-band), employing a temporal periodic sampling and dispersive delay scheme. The proposed design is validated through proof-of-concept experiments.
