Temperature-Dependent Gain Variation Reduction in -Band Erbium-Doped Fiber Amplifier Using Phosphorus-Erbium-Doped Silica Fiber

We propose a new technique to reduce the temperature-dependent gain (TDG) tilt of erbium-doped fiber amplifier in the C-band by supplying a composite optical gain block, conventional aluminum-rich erbium-doped fiber (EDF) serially concatenated with a special EDF composed of phosphorus-doped silica h...

Zusammenfassung:We propose a new technique to reduce the temperature-dependent gain (TDG) tilt of erbium-doped fiber amplifier in the C-band by supplying a composite optical gain block, conventional aluminum-rich erbium-doped fiber (EDF) serially concatenated with a special EDF composed of phosphorus-doped silica host, which showed opposite TDG coefficients in the C-band. The TDG variation was suppressed to less than plusmn0.45 dB for the saturated gain of 16 dB in 1525-1565 nm, within the temperature range of -40degC to +80 degC
