Paper Abstract

A transfer matrix analysis based on the Green's function method is used to derive the expression for the spectrum of a three-section phase-controlled DFB laser. This is of particular interest for implementating a continuously tunable optical filter. The influence of various parameters, such as phase shift and reflectivity, on the spectral behavior are studied theoretically. Analysis shows that a three-section DFB laser presents a single-mode spectrum over a wide continuous tuning range of around 2 nm. This result is very interesting for coherent and WDM systems.
