RESUMO

Coherente reflectometry has been an important technique for characterization of optinal and optoeletronics devices used in communications systems. In this work, Coherente frequency domain reflectometry was used in the study of the Distributed-Feedback Semiconductor lasers characteristics. The measurement of thermal response of the laser module, linearity of the frequency sweep and frequency instabilities induced by feedback light reflected at the systems conections was was done. With these informations it is possible to know some limitations of the technique.
