A Study on Optical Interconnects to Improve On-Chip Wireless Communication using Plasmonic Nanoantennas and Seeking Dielectric Nanoantenna as an alternative

Today’s wireless communication technology mainly makes use of radio waves and microwaves. These electromagnetic waves are transmitted and received using antennas. Recently emerged free space optical communication technology uses light waves traveling in free space to transmit data signals. For this our bigger antennas are replaced by minute optical nanoantennas. A main problem faced in optical communication technology is insufficient electromagnetic spectrum initialization. Nanoantennas are capable of solving this problem to a certain extent. The concept of optical nanoantennas is still in the very first phase of evolution. Developments in nanotechnology have improved nanoantenna fabrication techniques. So, a theoretical study of nanoantennas is highly desirable. This review paper provides an insight into various aspects of nanoantennas. A comparison between different types of nanoantennas is also done.
