S/S+ Band Tunable Thulium Doped Fiber Laser Anchored on 50 GHz ITU T Grid

We demonstrate a S/S+ band tunable thulium doped fiber laser (TTDFL) anchored on 50GHz ITU-T Grid. Over 57nm of tuning range (1454.9 ~1512.0 nm) covering most of the Thulium bandwidth and more than 8dBm output power has been obtained with the pigtailed solid eta Ion filter and dual wavelength (1.5 μ
