Abstract

Laser-induced graphene (LIG) has received a large amount of attention because of its superior properties of high electrical conductivity, high thermal stability and conductivity, simple synthesis, and the low fabrication cost of the patterned structures. However, most studies on LIG are focused on electrical applications. In this work, we first examine the effect of the substrate on LIG generated on polyimide and then fabricate the patterned LIG structures including gratings and Fresnel zone plates for terahertz (THz)-wave modulations. The functions of the structures are experimentally demonstrated by a THz focal plane imaging system. It is anticipated that LIG-based structures could widen the application of THz technology.
