title: Room-temperature multiwavelength erbium-doped fiber ring laser employing sinusoidal phase-modulation feedback.
abstract: An effective method for achieving a room-temperature multiwavelength erbium-doped fiber ring laser is presented. Simultaneous multiwavelength lasing with 0.5-nm intervals is achieved both experimentally and theoretically by addition of sinusoidal phase modulation in the ring cavity to prevent single-wavelength oscillation.
