Analysis of coupling efficiency between two holey fibers using a holographic coupler

This paper presents an approach for calculating coupling efficiency in a holey fiber holographic coupler system. There are two main contributions of this work. First, the current work is an attempt to analyze the coupling efficiency between two holey fibers for the first time using a holographic coupler. Second, our numerical analysis provides some insight for optimizing the coupling efficiency between two holey fibers by changing the relative hole size, diameter of the core of the fiber. Further our results are found to be in good agreement with results of coupling efficiency due to splicing in literature qualitatively.
