We demonstrate a novel single-polarization Er3+-doped fiber Fabry–Perot laser. The all-fiber Fabry–Perot cavity is simple inasmuch as it is formed by only two fiber-based components, a fiber loop polarizer and a wavelength-selective fiber loop reflector. The threshold power is 6.5 mW, the slope efficiency is 12.2%, and the extinction ratio is approximately 25 dB.
