Development of Silicon Grating-to-Grating coupling technology and Demonstration of Fan-In/Fan-Out for Multi-Core Fiber applications

Motivated by the potential applications of the multicore fibers (MCFs), we presented a compact solution for dense on-chip interconnects utilizing grating-to-grating coupling technology. In this work, we designed, fabricated and performed measurements of compact chip-based fan-in/fan-out structures fabricated on a silicon chip. We demonstrated a miniaturized chip-based component that can be applicable as an interposer for coupling light from 7-core MCF to individual channels on chip or as a chip-to-chip link between photonic integrated circuits (PICs).
