Abstract

We experimentally demonstrate the impact of a section of passive Erbium doped fiber (EDF) within linear cavity multiwavelength Brillouin Erbium fiber Laser (MBEFL). The influence of such passive EDF section length on the tuning range and the lasing cavity threshold is experimentally presented. The lasing threshold of the MBEFL in case of without and with different passive EDF2 section lengths is presented. A comparison is made between the traditional linear BEFL cavity and the BEFL cavity that utilized different passive EDF lengths of 1m, 3m, and Sm. Different 1480 pump power range (25-150) mW is used in the investigated study. The proposed configuration show significant increment in the tuning range for all passive EDF2 lengths as compared to the conventional BEFL cavity. Sm of passive EDF2 length exhibits higher tuning range of about 28nm at 100mW as compared to the 24.4nm tuning range at the same 1480 pump power using 1m of passive EDF2. All passive EDF2 lengths were compared in term of tuning range at different 1480 pump power range (25-150) mW.
