Abstract
As the SG-DBR laser is among the most attractive sources for WDM and DWDM systems, it is important and necessary to investigate its wavelength switching characteristics. This behaviour will affect wavelength routing and the capability limits for channel re-allocation in future optical networks. This paper presents detailed experimental studies on a high-speed SG-DBR laser by using a Fabry–Perot Interferometer technique adapted for the non-continuous wave case. Measurements of fast intra-modal (i.e. cavity mode) and inter-modal (i.e. super-mode) wavelength switching and insights into the device's dynamic behaviour are obtained. Implications are given for transmitter design in dynamic wavelength routing and channel re-allocation.
