• PMF grating
• Single polarization

The switchable single polarized Er-doped polarization-maintaining-fiber (PMF) linear cavity laser based on two PMF gratings has been proposed. The gratings are fabricated in Er-doped PMFs, each grating has two single polarized wavelength and they function as the reflective mirror of the laser. So the laser can output switchable single wavelength polarized laser, with the switchable of the wavelength of grating the output of the laser can also be switched. Our experiment result shows that the laser has the OSNR of 48.5 dB, the degree of polarization (DOP) of 98.7%, and the laser linewidth with less than 9.2 pm.
