Abstract :
A multichannel filter formed by the piezoelectric transducer (PZT)-induced phase shift in a phase-only sampled fiber Bragg grating (FBG) is experimentally demonstrated. The PZT-induced phase shift is stable and the magnitude of the induced phase shift is controllable. As an important application of this multichannel filter, a semiconductor optical amplifier (SOA)-based multiwavelength fiber ring laser is successfully demonstrated.
