Paper Abstract

The design and performance of a novel circuit working with a Gallium Arsenide multiquantum well p-i-n modulator is reported. The circuit can rapidly compensate for the temperature dependent shift of the excitonic energy position of quantum confined stark effect modulators. The energy position remains invariant over a temperature of 10K. The circuit is simple and can be operated with a single device or an array of modulators. I .
