Abstract

A seven-core few-mode multicore fiber in which each core supports both the LP₀₁ mode and the two degenerate LP₁₁ modes has been designed and fabricated for the first time, to the best of our knowledge. The hole-assisted structure enables low inter-core crosstalk and high mode density at the same time. LP₀₁ inter-core crosstalk has been measured to be lower than -60 dB/km. LP₁₁ inter-core crosstalk has been measured to be around -40 dB/km using a different setup. The LP₁₁ free-space excitation-induced crosstalk is simulated and analyzed. This fiber allows multiplexed transmission of 21 spatial modes per polarization per wavelength. Data transmission in LP₀₁/LP₁₁ mode over 1 km of this fiber has been demonstrated with negligible penalty.
