Abstract
Some examples described herein provide for controlling output modulation amplitude for optoelectronic devices. In an example, a method includes transmitting a first data pattern to an optical modulator device. The method also includes determining, while transmitting the first data pattern and for each heater control value of a plurality of heater control values for a heater, a photodiode current value associated with the optical modulator device to generate a plurality of photodiode current values corresponding to the plurality of heater control values. The method also includes determining a maximum optical modulation amplitude for the optical modulator device based at least in part on the plurality of photodiode current values corresponding to the plurality of heater control values. The method also includes controlling the heater for the optical modulator device based on the maximum optical modulation amplitude.
