Abstract

This study presents a fan-in coupler architecture for a four-core fiber, implemented using a single diffractive optical element (DOE). The DOE selectively excites two opposite cores while the remaining ones serve as receiving channels. The DOE was designed using an iterative algorithm, resulting in a computer-generated hologram and fabricated using two-photon polymerization (TPP). Numerical simulations and experimental measurements confirmed correct operation of the concept. The proposed coupler shows strong potential for applications in fiber-optic sensing and optical communications.
