Abstract

Laser-induced graphene (LIG) has received extensive attention due to its excellent properties such as high electrical conductivity, high thermal stability and electrical conductivity, simple synthesis, and low manufacturing cost of patterned structures. However, most research on LIG has focused on electrical applications. In this work, we first examine the influence of the substrate on the LIG generated on polyimide, and then fabricate patterned LIG structures, including gratings and Fresnel zone plates for terahertz (THz) wave modulation. The function of the structure is proved through the experiment of the terahertz focal plane imaging system. It is expected that the LIG-based structure can widen the application of THz technology.
