We report the design and performance characteristics of a voltage feedback circuit which can rapidly compensate for the temperature-dependent shift of the excitonic peak energy positions in quantum confined Stark effect modulators. The energy position remains invariant over a temperature shift of 10°. The circuit is simple and can be operated with a single device or an array of modulators.
