This document specifies measurement methods of a half-wavelength voltage and a chirp parameter applicable to MZMs in microwave and millimeter-wave RoF systems. In addition, these methods are also effective for the estimation of the intermodulation distortions and transmission performances. The methods apply for the following:
-
frequency range: 5 GHz to 110 GHz;
-
wavelength band: 0,8 μm to 2,0 μm;
-
electro-optic material based MZMs and their modules.
