Measurement method of a half-wavelength voltage for Mach-Zehnder optical modulator in wireless communication and broadcasting systems. | Status: Current

1 Scope This document specifies a measurement method of half-wavelength voltage applicable to Mach-Zehnder optical modulators in wireless communication and broadcasting systems. In addition, this method is also effective for the estimation of the intermodulation distortion of Mach-Zehnder optical modulators. The method applies for the following:

• – frequency range: 10 MHz to 30 GHz;
• – wavelength band: 0,8 µm to 2,0 µm;
• – electro-optic material based Mach-Zehnder optical modulators and their modules.
