Packaging silicon photonic chips is challenging due to mode field diameter mismatches between silicon waveguides (0.3 – 0.5μm) and single-mode fibers (9μm). FAs address this with high integration. Mode Field Diameter Conversion FAs (MFD FAs) further improve coupling by splicing ultra-high numerical aperture fibers, enabling conversions like 3.2 – 5.5μm to 9μm. For multi-channel silicon optical modules, FAs separate signals across parallel fibers. Curved fiber channels in arrays reduce crosstalk, ensuring reliable transmission.
