Abstract

Wavelength-tunable semiconductor lasers have found widespread applications in many fields, such as optical communication systems and high-resolution spectroscopy, due to their wavelength-flexibility and reconfigurability. Wavelength-tunable semiconductor lasers with low phase noise are important in applications where coherent detection scheme is required, so it is therefore imperative to have a good understanding of the phase noise of these devices. This talk will present our investigations on the complicate phase noise characteristics of the wavelength tunable semiconductor lasers, and will specifically demonstrate results with two types of multi-section DBR based laser (the SGDBR and the MGY devices) for their applications in coherent systems.
