Erbium-Doped Fiber Amplifier with Extended L-Band Gain to 1625 nm

Not Accessible

Your library or personal account may give you access

Abstract

We report a double-pass L-band erbium-doped fiber amplifier providing ≥20dB gain from 1565-1625nm, with 46dB maximum gain at 1600nm. At 1625nm, the NF, OSNR, gain coefficient, and temperature-dependent-gain-coefficient were 7.2dB, 25dB, 0.045dB/mW, and -0.037dB/oC, respectively.
