چکیده
The wavelength tuning is an important issue for distributed feedback (DFB) lasers designs and applications. In this paper we have presented an algorithm to analyze the wavelength tuning characteristics of twosection index-coupled (TS-IC) DFB lasers in above threshold regime, by the means of the transfer matrix method (TMM), and the carrier rate equation. The versatility of the theoretical model in the present work is demonstrated in an analysis of static characteristics of TS-IC-DFB lasers, which illustrated the important influence of coupling coefficient, cavity condition and injection current on the wavelength tuning. Therefore, The TS-IC-DFB lasers will be useful in optical communication systems using wavelength division multiplexed (WDM) networks.

A new integrated optical sensor chip is proposed, based on a modified distributedfeedback (DFB) semiconductor laser. The semiconductor layers of different refractive indices that comprise a laser form the basis of a waveguide sensor, where changes in the refractive index of material at the surface are sensed via changes in the evanescent field of the lasing mode. In DFB lasers, laser oscillatio...
