Abstract

A new approach for remote reflectivity detecting based on optical feedback effect in distributed feedback (DFB) lasers is presented. A linear dependent relationship between the reflectivity of external target and the signal modulation depth is obtained. The experimental results show a good agreement with the theoretical analysis and the simulation, and indicate that the active sensing based on optical feedback effect in DFB laser is an effective approach for reflectivity detecting. With the advantage of simple and compact structure, this application can easily enhance the development of a new generation of active sensor.
