Abstract
Some examples described herein provide for controlling output modulation amplitude for optoelectronic devices. In an example, a method includes transmitting a data pattern to an optical modulator device. The method also includes identifying, for each heater control value of a plurality of heater control values for a heater thermally coupled with the optical modulator device, an optical modulation amplitude corresponding to the heater control value based on a corresponding photodiode current value identified while transmitting the data pattern. The method also includes determining a maximum optical modulation amplitude for the optical modulator device based on a plurality of optical modulation amplitudes corresponding to the plurality of heater control values according to the identifying. The method also includes controlling the heater based at least in part on the determined maximum optical modulation amplitude that has been modified according to scaling maximum photodiode current values.
