Injection-Seeded Actively Mode-locked Erbium-Doped Fiber Ring Laser for Frequency Measurement in Telecommunication Band
AbstractIn this paper the mode-locking of an erbium-doped fiber ring laser with frequency shifted feedback is described. We use the configuration with an acousto-optical modulator inserted in the laser cavity that produces 1.7 ps pulses with a 40 MHz repetition frequency. The corresponding optical frequency comb has a bandwidth of more than 10 nm, centered at 1558 nm. The laser operates with external injection from a DFB telecommunication laser diode which can be used for controlling the offset frequency of an optical comb. To our knowledge, this is the first demonstration of external injection of a mode-locked fiber laser using a telecommunication laser diode.
