Abstract: Here we report a detailed numerical investigation into the effects of asymmetric cores on the modal properties in multimode fibers (MMFs). Three asymmetric core shapes combine with three core structures, respectively, forming nine kinds of common asymmetric cores in our simulation. The discussed modal properties include mode number, birefringence, effective index, power confinement factor, fiber loss, effective mode area, and differential mode delay. An evaluation factor called mode-NSD is proposed to integratedly judge the nonlinearity and compatibility ability in the MME Finally, the manufacturing tolerance with the size variation up to 5% is also discussed for practical needs. These numerical results are beneficial for the comprehensive assessment of the space-division-multiplexing optical fibers with asymmetric cores. (C) 2021 Optical Society of America
