Highly birefringent 98-core fiber

Opt Lett. 2014 Aug 1;39(15):4568-70. doi: 10.1364/OL.39.004568.

Abstract

We report on the fabrication and characterization of a polarization-maintaining multicore fiber. The fiber has 98 aligned cores, each with a birefringence of ≈2.3×10-4. The beat length, polarization extinction ratio, and polarization orientation are characterized.
