In this work we report on an experimental interferometric technique capable to measure the degree of phase correlation between two or more laser modes and to measure the linewidth of the corresponding THz-wave signal when the modes are photomixed. The method is applied to a Fabry-Perot laser and two mutually-coupled integrated DFBs.

Abstract
In this work we report on an experimental interferometric technique capable to measure the degree of phase correlation between two or more laser modes and to measure the linewidth of the corresponding THz-wave signal when the modes are photomixed. The method is applied to a Fabry-Perot laser and two mutually-coupled integrated DFBs.File in questo prodotto:
