| Summary: | We report what is to our knowledge the first fiber distributed-feedback laser using a single Bragg grating at 1.5µm written directly into a 2-cm-long Er<sup>3+</sup>-doped fiber codoped with Yb<sup>3+</sup>. We obtained robust single-frequency operation by either using one end reflector or locally heating the center of the grating to create the necessary phase shift. |
