1×2 Equilateral Triangular Dielectric Resonator Nantenna array for optical communication

Abstract

In this paper, we explore the potential benefits of designing a dielectric resonator nantenna shaped in an equilateral triangular manner which is fed via a 1×2 corporate feed network. Utilizing full wave electromagnetic simulation software CST MWS, we demonstrated our proposed nantenna to work as a transceiver at optical C-band (1.55 µm) having a center frequency of 193.5 THz. Numerical results demonstrate that the proposed nantenna exhibits an end-fire directional radiation pattern of 9.57 dB with a wide impedance bandwidth of 2.58 % (189 THz – 194 THz) covering the standard optical C-band transmission window. The proposed nantenna can be a viable candidate for applications used in nanophotonics, inter and intra network optical wireless communication devices, optical sensing and optical energy harvesting etc.
