Paper Abstract

A Brillouin/erbium fiber laser (BEFL) of 25km single-mode fiber is constructed, and its characteristics of optical carrier suppression are measured and analyzed. Light wave modulated by an electro-optic intensity modulator (EOIM) with 11GHz microwave frequency is adopted as the testing light. As much as 32 dB optical carrier-suppression ratio is achieved at 112mW of 980nm pump power inside the BEFL. Meanwhile, the sideband powers remain nearly unchanged in the process. Moreover, the carrier-suppression ratio is precisely controllable by tuning the 980nm pump power in the BEFL. These optical carrier-suppression characteristics promise significant applications of such a technique not only to distributed Brillouin optical fiber sensing based on EOIM but also to microwave photonic signal processing.
