Abstract
The group delay difference between modes of multicore optical fiber cores is studied by the interference method using a Mach–Zehnder interferometer and a low-coherence radiation source. The data obtained show that the group delay difference between multicore optical fiber cores is caused by optical fiber bending and increases with decreasing winding radius.
