A narrow linewidth (Δλ < 0.07 nm), low noise, widely tunable Er:Yb ring fiber laser is demonstrated using a fiber Bragg grating mirror embedded in a 3D printed polymer beam. By bending the polymer beam, continuous tuning of the laser was achieved over 30 nm, from 1543 nm to 1574 nm, with power variation below 1 dB, showing high temporal and spectral stability and a signal-to-background value exceeding 50 dB. These results present a versatile and simple method for tailoring tunable narrow-linewidth lasers.
