Abstract :
Gradient descent optimization algorithm is applied to design few-mode Er3+-doped fibers adapted to gain equalization over modes and wavelengths, for mode division multiplexing. Theoretical study is performed for fiber designs supporting six and ten spatial modes at signal wavelength. Flat gain is obtained by optimizing Er3+ doping profile of a micro-structured core and modal composition of the pump beam.
