Stabilized dual-wavelength erbium-doped dual-ring fiber laser.
A stable dual-wavelength erbium-doped fiber (EDF) compound ring laser using a double-ring filter (DRF) is proposed and demonstrated experimentally. By using a ring filter incorporated within the ring cavity, the fiber laser can lase two wavelengths simultaneously. The dual-wavelength output exhibits a good performance having the optical side-mode suppression ratios (SMSRs) of 45.3 and 46.3 dB and output powers of -8.1 and -7.1 dBm, respectively. In addition, the optical output stabilities of the ring laser have been also discussed.
