摘要：
We developed a narrow-linewidth linearly-polarized all-PM-fiber MOPA at the wavelength of 1610 nm. The MOPA consists of a DFB laser diode seed source and three amplifier stages with three different gain fibers. The first amplifier stage employed an Er doped fiber and the second and third amplifier stages employed Er: Yb co-doped fibers. The maximum output power was 8 W. Linewidth of 25 MHz and polarization extinction ratio of 28 dB was obtained. At the maximum output power, no ASE component around 1.55 mu m or 1 mu m was observed. (C) 2016 Optical Society of America
