✦ Synopsis

and 65 mW, respectively. The best performance was reached at about 0.5 mm sag.

CONCLUSION

We have equalized, for the first time, the gain spectrum of an EDFA around the 1532 nm band by using tunable LPFGs. The ASE peak of an EDFA around the 1532 nm wavelength was equalized by 7.5 dB, and the gain peak by 3 dB at 37 mW pump power. The result can be improved further by more accurate design of the LPFGs.
