|摘要:||This study investigates, for the first time, static and dynamic wavelength switching characteristics of the 1.3 mu m quantum-dot vertical-cavity surface-emitting laser (QD VCSEL). The free-running QD VCSEL with lambda 1 and lambda 2 state innately is injected by a laser source with lambda 1 state. When the injection power exceeds the threshold power, the dominant state of the QD VCSEL changes from lambda 2 to lambda 1 state. Results of this study demonstrate that the wavelength switching based on a 1.3 mu m QD VCSEL has a simpler and more cost-effective configuration than those of previous systems.|
