Gain equalization of EDFA using a loop filter with a single polarization controller

Gain equalization of EDFA using a loop filter with a single polarization controller

A Sagnac loop filter with two pieces of high birefringence fiber having equal lengths, and spliced together at a fixed angle of 30o displacement between the two principle axes, is proposed in this letter. Gain equalization of erbium-doped fiber amplifiers (EDFAs) is implemented by tuning only the po...
