    This study investigates, for the first time, static and dynamic wavelength switching characteristics of the 1.3 μm quantum-dot vertical-cavity surface-emitting laser (QD VCSEL). The free-running QD VCSEL with λ1 and λ2 state innately is injected by a laser source with λ1 state. When the injection power exceeds the threshold power, the dominant state of the QD VCSEL changes from λ2 to λ1 state. Results of this study demonstrate that the wavelength switching based on a 1.3 μm QD VCSEL has a simpler and more cost-effective configuration than those of previous systems.
