Abstract
In this letter we propose, for the very first time, a Molybdenum based Yagi-Uda high-directional nantenna. It is realized using simple Low Pressure Chemical Vapor Deposition (LPCVD) technique on a silicon substrate for 1550nm standard optical communication system. The proposed nantenna uses Molybdenum metal as a ground plane while the Yagi-Uda driven, radiator and directing elements are made up of Aluminum. Grounded Co-Planar Waveguide (GCPW) technique is used for exciting the nanoantenna in CST Microwave Studio simulator. The nantenna achieves an impedance bandwidth of (193.37-193.71THz) at a center frequency of 193.5THz with a high gain and directivity of 12.9 and 16.6 dB, respectively. Near-field and far-field performance of the proposed nantenna is also demonstrated via extensive numerical simulations. The results achieved makes the proposed nantenna a viable candidate for applications in the field of nanophotonic circuits and photovoltaic devices working in the optical C-band window.
