We report what is to our knowledge the first fiber distributed-feedback laser using a single Bragg grating at 1.5 μm written directly into a 2-cm-long Er3+-doped fiber codoped with Yb3+. 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.
