The objective of this work is to develop superdirective nanoantennas (NAs) with the capability of concentrating radiated light into a narrow angular region that can serve for the realization of point-to-point wireless links and efficient optical nanocouplers for application in photonic integrated circuits (PICs). The proposed NAs consist of a superdirective meta-array of nanoscale plasmonic split ring resonators (SRRs) operating at the optical telecommunication wavelength of 1500 nm. These NAs have a substantially planar architecture and can be fabricated using standard CMOS technology for realization of multi-layered PICs. The performance of sample configurations of the proposed superdirective meta-arrays is verified with numerical fullwave simulations.
