Abstract :
Carrier lifetime measurements are an important tool for studying the properties of semiconductor lasers. We present, for the first time, an approach to determining the differential lifetime of quantum well lasers which consists of adding an impedance stabilization circuit to the traditional small signal optical response technique, thus providing a constant current modulation regardless of the laser impedance
