Title :
Frequency modulation properties of erbium doped DFB fiber lasers using cavity strain
Author_Institution :
Naval Res. Lab., Washington, DC, USA
Abstract :
Frequency modulation of a DFB fiber laser below 50 kHz is demonstrated using cavity strain applied by a piezoelectric element. Uses of this technique are discussed along with the likely cause of associated intensity modulation induced by the cavity strain.
