Main Results:

Strong multiple scattering between nanoparticles significantly influences coupling efficiency.
Optimizing directionality led to decreased coupling efficiency.
Achieved up to 30% transmission into a single direction due to a balance between scattering and directionality.
Demonstrated low group delay dispersion for coupling pulses as short as 50 fs.

Conclusions:

Metallic nanoparticle antennas can enable efficient, low-dispersion light coupling into silicon waveguides.
Multiple scattering and directional control present a fundamental trade-off in antenna design.
The reported system is suitable for high-speed optical communication applications.
