Paper Abstract

The gain media of the quantum dot lasers consist of InAs QDs in an InGaAsP matrix on an InP substrate. The quantum dot lasers have different free spacing ranges (FSRs) corresponding to Fabry-Pérot (F-P) cavity lengths. A silicon ring resonator and a QD laser have been combined to form comb laser. The output characteristics of the combined comb laser were investigated. The measured FSR was about 2.8nm and the extinction ratio was about 10(dB) when the FSR of the QD laser was about 0.4nm and the FSR of the ring resonator was about 0.47nm. The experimental results show that the ring resonator had a strong control on the FSR and extinction ratio of the comb laser.
