METHOD FOR MEASURING MISMATCHING OF ULTRA-HIGH-SPEED PHOTONIC SAMPLING CLOCK IN MULTIPLE CHANNELS, AND MEASUREMENT AND COMPENSATION DEVICE

摘要

A measurement and compensation device for the mismatching of an ultra-high-speed time and wavelength-interleaved optical pulse in sequence channels and a method therefor, comprising a module for generating an ultra-high-speed time and wavelength-interleaved optical pulse to be measured (1), an optical spectrum analysis module (3), a radio spectrum analysis module (4), and a data analysis and processing module (5). By performing measurement and analysis on the frequency domain of the ultra-high-speed time and wavelength-interleaved optical pulse sequence, the mismatching information of each channel pulse sequence is obtained, thereby overcoming the bottleneck of insufficient sampling rate of time domain observation method performed by an oscilloscope. The obtained channel mismatching information can further serve as the foundation for compensation and correction for the mismatching in ultra-high-speed time and wavelength-interleaved optical pulse sequence channels.
