Abstract :
The electroabsorption modulator still shows large transient chirp and thus is hard to operate at higher bit rate without a high insertion loss. To overcome this obstacle, it is imperative to fully understand the chirp characteristics caused by Stark effect in the multiple quantum-well (MQW) structures. This work presents a simple experimental method of measuring MQW electro-absorption and the chirp parameter
