Wavelength-Spacing Tunable Multi-wavelength Fiber Lasers Based on Hybrid Gain Medium and Mach-Zehnder Interferometer

摘要

Wavelength-spacing continuously tunable multi-wavelength fiber lasers based on a Mach-Zehnder interferometer comb filter are achieved. Stable multi-wavelength lasing based on hybrid gains of Erbium-doped fiber amplification and fiber Raman amplification (semiconductor optical amplification) is demonstrated.
