PLASMONIC NANOANTENNA FOR POSSIBLE CMOS INTEGRATION

Plasmonic nanoantennas have gained interest in several environments like integrated photonics, biosensing, microscopy and solar cells, due to their capability in collecting and conveying the electromagnetic radiation in the visible and in the near visible regions. However, examples of antennas applied to integrated circuits are conspicuously rare even if they are able to provide a solution to the bandwidth shortage problem. In this work I have developed a new plasmonic nanoantenna configuration able to be easily coupled with a transmission line in order to enable the direct connection with plasmonic modulators and demodulators. Furthermore, the antenna shows a tunable double resonance that allows for bidirectional communications without the use of complex TDD techniques. The size of the antenna and the materials employed are all suitable for future CMOS integration.
