摘要：

We demonstrate direct and efficient optical coupling from an optical fiber into plasmonic integrated circuits (PICs) at 1.55-mu m wavelength using ultra-compact plasmonic dipole nanoantennas. The PICs consist of slot waveguides with single-chip integrated Yagi-Uda antennas. To improve the optical coupling efficiency from optical fibers, we add 500-nm-thick Su-8 film with a high refractive index as the top cladding. We experimentally achieve 8.6% couple-in efficiency from a high numerical aperture fiber to the plasmonic slot waveguide and 46% total couple-out efficiency from the plasmonic slot waveguide. We also quantitatively characterize the dependence of the couple-in efficiency to the spot size of the incident light.
