Abstract-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 ±0.45 dB for the saturated gain of 16 dB in 1525-1565 nm, within the temperature range of -40°C to +80 °C.
