Low Loss Optical Connection Module for Seven-Core Multicore Fiber and Seven Single-Mode Fibers

摘要

A pair of compact optical connection modules that connect seven-core multicore fiber and seven single-mode fibers is developed. Insertion loss of ${<}{rm 0.6}~{rm dB}$, polarization-dependent loss of ${<}{rm 0.1}~{rm dB}$, and crosstalk of ${>}{rm -50}~{rm dB}$ are observed. The structure is applicable to the multicore fiber with more than seven cores.
