Abstract
Examples described herein relate to a method for synchronizing a wavelength of light in an optical device. In some examples, a heater voltage may be predicted for a heater disposed adjacent to the optical device in a photonic chip. The predicted heater voltage may be applied to the heater to cause a change in the wavelength of the light inside the optical device. In response to applying the heater voltage, an optical power inside the optical device may be measured. Further, a check may be performed to determine whether the measured optical power is a peak optical power. If it is determined that measured optical power is the peak optical power, the application of the predicted heater voltage to the heater may be continued.
