Abstract

The Brillouin-Erbium Fiber Laser (BEFL) has shown great potential as a multiwavelength source for the dense wavelength division multiplexing system. However, mode competition that exists in the laser cavity confines the wavelength tunability and number of Stokes of the BEFL. In the literature, a Tunable Bandpass Filter (TBF) was adopted in the linear BEFL to improve the tuning range and number of Stokes. This research works examines the effects of different bandwidths of TBF in a multiwavelength BEFL. The linear gain medium was provided by a 13 m long Erbium Doped Fiber (EDF) pumped by a 980 nm laser diode. A 7 km Single Mode Fiber (SMF) was placed in the cavity between the EDF and TBF, and a Brillouin Pump (BP) was externally pumped to produce a non-linear gain from the SMF fiber. The measurements were carried out to study the performance of the multiwavelength BEFL with and without the utilisation of the TBF. Two TBF bandwidths were used in this experiment, namely 3 nm and 1 nm.
