Abstract :
We propose and demonstrate a novel method to characterize the coupling coefficient and loss coefficient of a distributed Bragg reflector (DBR). The method is based on a coupled-mode analysis of periodic structures, and involves the linewidth comparison of a pair of DBR Fabry-Pérot resonators. The method is shown to be independent of coupling efficiency and wavelength dependence of the DBR parameters.
