Abstract :
The relative intensity noise (RIN) of both a two-section and a three-section tunable multiple-quantum-well distributed-Bragg-reflector (MQW-DBR) laser operating at 1.53 mu m is discussed. It is found that the RIN can be modeled using a single-mode rate equation, which neglects the frequency dependence of the Bragg reflector, and that the RIN is independent of tuning current for fixed output power.<>
