Simulation of terahertz photonic integrated antenna


The rapid development of wireless devices, that take place over the last decade, is associated with an increase in the need to achieve a higher data transfer rate. To achieve this goal, it is necessary to use the terahertz (THz) range. The vast majority of THz devices (no matter bulk or integrated) require fast, non-mechanical beam shape control, which is generally defined as the ability to manipulate the shape of the radiation pattern in the desired way. But it is hard to implement without the use of photonic integrated phased array antennas. In this paper, the possibility of the creation of photonic integrated antenna which is a basic element of such a system is investigated and confirmed. The antenna is based on a platform of metamaterial silicon with perforations, the dimensions of which are in the deep subwavelength region, which makes it possible to provide a wide bandwidth with low dispersion.
