Abstract
An all fiber, diode-pumped, electrically tunable ring laser is reported. Gain is provided by an erbium-doped fiber and tuning by a Fiber Fabry-Perot etalon. The threshold at 1.566 µm is 2.9 mW, the slope efficiency is 0.15 and the output power is 4.2 mW with 32 mW of pump power. The output wavelength can be tuned from 1.525 to 1.586 µm with a variation in power of less than 3.5 dB.
