Design strategies for two-core uncoupled multicore fiber for crosstalk analysis

In order to achieve the low-crosstalk behavior in uncoupled homogeneous multicore fibers, the design strategies for two cores have been discussed. The relationships between inter-core crosstalk and fiber parameters, such as core radius, core pitch, relative refractive index difference, etc. have been explored in order to maintain the single mode propagation through the cores of uncoupled multicore fiber.
