Project Description

Photomixers are one of the most promising sources of continuous-wave terahertz (THz) radiation with excellent frequency tunability and high spectral purity while operating at room temperature. The objective of this project is to develop a new generation of high-performance photomixers that enable new functionalities for practical THz imaging, sensing, and communication systems that are not possible through existing technologies. Specifically, we plan to utilize plasmonic nanostructures inside photomixer active area to enhance its optical-to-THz conversion efficiency and THz radiation power by several orders of magnitude. This project will enable student to understand and design nano-plasmonic structures in industry standard electromagnetic simulators. The student will also be able to participate in the nano-fabrication process of these structures (under the supervision of an expert postdoc) in KAUST nano-fabrication facilities.​​​​
