Single output polarization control of fiber DFB laser using injection locking

Optical Fiber Communication Conference and Exhibit, Anaheim, CA, 17-22 March 2002The output polarization of a fiber distributed feedback laser was stabilized using an active injection locking technique. Distributed feedback fiber laser was fabricated by scanning a phase mask in a 5 cm long hydrogenated Er/Yb fiber using a 248 nm excimer laser. Injection locking was achieved by fine-tuning the operating temperature of the Fabry-Perot laser diode. Linear polarized output with degree of polarization larger than 95% and side mode supression ratio higher than 45 dB was achieved.Department of Electrical EngineeringDepartment of Electronic and Information EngineeringRefereed conference pape
