Linearly polarized Er3+-doped fiber laser by use of a fiber loop polarizer and a wavelength-selective fiber loop reflector

摘要

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. (C) 1998 Optical Society of America. [References: 11]
