Hybrid Plasmonic Waveguide Fed Broadband Nanoantenna for Nanophotonic Applications

In this letter, we propose a novel hybrid plasmonic waveguide fed broadband optical patch nanoantenna for nanophotonic applications. Through full wave electromagnetic simulation, we demonstrated our proposed antenna to radiate and receive signal at all optical communication windows (e.g., λ = 850, 1310, and 1550 nm) with ~86% bandwidth within the operational domain. Moreover, numerical results demonstrate that the proposed nanoantenna has directional radiation pattern with satisfactory gain over all three communication bands. In addition, we evaluated the antenna performances with two different array arrangements (e.g., 1-D and square array). The proposed broadband antenna can be used for prominent nanophotonic applications, such as optical wireless communication in interchip and intrachip devices, optical sensing, and optical energy harvesting.
