Temperature invariance of quantum well modulators using a feedback circuit based on the quantum confined Stark effect.
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 degrees . The circuit is simple and can be operated with a single device or an array of modulators.
