Terahertz wave modulation properties of graphene with different excitation laser power

Abstract

Terahertz wave modulation properties of graphene are investigated using an external 975 nm continuous wave laser. The modulation depth of monolayer graphene and 3-layer graphene was 16% and 32% under 1495 mW excitation power.

“…7 THz radiation is frequently used in fields such as medical imaging, 8 public security, high-speed communications, and other fields such as metrological applications, as well as in 6G technology for next-generation communication sectors. [9][10][11][12][13] We know that THz radiation is also important for molecular and biomolecular detection, and its absorption in molecular and biomolecular systems is primarily driven by the excitation of intra-and intermolecular vibrations in which there are weakly bound molecular entities with hydrogen bonds. It is also responsible for weak interactions such as van der Waals forces.…”
