New method enhances frequency conversion processes in graphene

Researchers from Canada’s University of Ottawa, Iridian Spectral Technologies and University of Bayreuth in Germany have developed combined methods to enhance THz nonlinearities in graphene-based structures. The team’s innovative methods aim to enhance frequency conversion of terahertz (THz) waves in graphene-based structures, unlocking new potential for faster, more efficient technologies in wireless communication and signal processing.

THz waves, located in the far-infrared region of the electromagnetic spectrum, can be used to perform non-invasive imaging through opaque materials for security and quality control applications. Additionally, these waves hold promise for wireless communication. Advances in THz nonlinear optics, which can be used to change the frequency of electromagnetic waves, are essential for the development of high-speed wireless communication and signal processing systems for 6G technologies and beyond.
