Abstract
A novel room-temperature multi-wavelength erbium-doped fiber ring laser is proposed. In this laser, four-wave mixing (FWM) is used to mitigate mode competition, achieving stable room-temperature multi-wavelength operation. Active mode-locking is incorporated to enhance the FWM effect, improving the amplitude flattening and spectral bandwidth of the multi-wavelength output. Stable simultaneous 42 wavelength lasing operation with 0.55 nm wavelength spacing within the 3 dB spectral band is experimentally demonstrated.
