Abstract :
A design concept of few-mode multicore fiber is presented. Cores with a step-index profile are designed to support two LP modes over the C band and the L band with a large effective area larger than 110 μm2. The pitch of cores is determined regarding the inter-core crosstalk related to the LP11 mode. The two LP modes multicore fibers with four cores and seven cores show a relative core multiplicity factor (RMCF) of 7.3 and 9.2, respectively. The RCMF of the proposed two LP modes multicore fiber is larger than that of previously reported single-mode multicore fibers.
