Abstract

A device includes a comparator configured to compare a transmission phase of light in a photonic component with a reference phase. The device further includes a heater configured to control a temperature of the photonic component. The heater includes a plurality of heater segments, and a plurality of switches, wherein each switch of the plurality of switches is between a pair of heater segments of the plurality of heater segments. The device further includes a controller configured to control operation of each switch of the plurality of switches based on results from the comparator for selectively connecting heater segments of the plurality of heater segments in series.
