To achieve miniaturization and low power consumption of chip-to-chip optical interconnects, which are essential for next-generation "All-Photonic Networks," we quantitatively evaluated the optical fiber coupling efficiency of a-Si metalenses. In the design process, a similarity model maintaining the numerical aperture (NA) was introduced to reduce the computational load. The metalenses, fabricated using electron beam (EB) lithography, were evaluated using an original experimental setup. The results experimentally confirmed the performance as designed and validated the effectiveness of the similarity model in predicting full-scale performance. These findings provide important guidelines for practical design. Further details will be reported at the conference.
