Abstract
Effect of absorption and amplification on dispersion properties of microstructure fiber is considered. Gain of high-order modes is analyzed. The adjustment of the radius of the central active core allows to achieve the optimal conditions for the lasing of fundamental mode in multimode microstructure fiber. Arrangement of multiple active cores allows exciting high-order modes selectively.
