Paper Abstract

A two-wavelength fiber laser with two π-equivalent phase shifts (EPSs) is studied and fabricated. The π-EPS is obtained through extending one sampling period by 50% in a fiber sampled Bragg grating (SBG). To get a two-wavelength fiber laser lasing in the -1st channel, two π-EPSs are introduced in the position of L/3 and 2L/3 in the SBG, where L is the total length of the SBG. A stable 22-pm-spaced dual wavelength DFB fiber laser is achieved in the experiment.
