METHOD AND APPARATUS FOR OPTICAL ASYNCHRONOUOS SAMPLING SIGNAL MEASUREMENTS

摘要

A method and a system for measuring an optical asynchronous sample signal. The system for measuring an optical asynchronous sampling signal comprises a pulsed optical source capable of emitting two optical pulse sequences with different repetition frequencies, a signal optical path, a reference optical path, and a detection device. Since the optical asynchronous sampling signal can be measured by merely using one pulsed optical source, the complexity and cost of the system are reduced. A multi-frequency optical comb system using the pulsed optical source and a method for implementing the multi-frequency optical comb are further disclosed.

1. A multifrequency optical comb source comprising:
a pulsed laser source with a laser cavity generating two or more optical pulse sequences in two or more spectra, where each of the two or more optical pulse sequences have different central wavelengths, where the maximum value of the full widths at half maximum of the two or more optical pulse sequences is less than the difference of the center wavelengths, where the repetition frequencies of the two or more optical pulse sequences with different center wavelengths are different; and a nonlinear optical apparatus, where one or more of the two or more optical pulse sequences pass through the nonlinear optical apparatus and one or more of the two or more spectra are broadened such that the two or more spectra of the two or more optical pulse sequences overlap.
