Abstract
The measurement of frequency responsibility is very difficult to carry out by swept-frequency method but instead of optical spectrum analyzer approach when the modulating frequency is higher than 50 GHz. We will present the measurement of modulation index in both of theoretical derivation and experimental demonstration in this paper.
