Abstract :
We developed simplified coupled-power equations including cladding modes, and revealed that crosstalk in tightly bent multi-core fibers can be increased from the existing predictions. The crosstalk increase was proportional to the square of the bend loss coefficient, and validated by experimental results, for the first time.
