Abstract
A description is given of a theory of wavelength tuning in two-segment distributed-feedback (DFB) semiconductor lasers. Continuous tuning with a range of at least several angstroms (more than 100 GHz) is feasible. For the first time the tuning mechanism of two-segment DFB lasers is explained in terms of the fundamental phase and amplitude reflection properties of the waveguide gratings. The theoretical framework developed provides physical insights into the wavelength tuning mechanism and can be used in the development of novel and more efficient tuning structures
