Abstract
Embodiments may relate to an optical modulator system. The optical modulator system may include a first photodiode to measure a first optical level at an output of a Mach-Zehnder modulator (MZM). The system may further include a second photodiode to measure a second optical level at a termination of the MZM. The system may further include a logic coupled with the first photodiode and the second photodiode, the logic to identify a modulator bias that minimizes the first optical level. Other embodiments may be described or claimed.
