| titleOfInvention | A method for processing a large-area terahertz polarizer without a substrate |
| abstract | The invention relates to a processing method for a large-area terahertz polarizer without a substrate. The processing method includes the following steps: Step S1: attaching an aluminum foil with a low-viscosity liquid on the surface to the surface of a Teflon substrate to eliminate gravity and air Due to the influence of the flow, the surface of the aluminum foil is flat during processing; Step S2: use a femtosecond laser processing system to cut a periodic slot structure on the surface of the aluminum foil, and keep non-periodic short-line connections between the metal wires; Step S3: remove the special Fluorocarbon substrate to obtain a terahertz polarizer. The substrate-free large-area terahertz polarizer processing method has the advantages of simple process, low cost, high production efficiency, stable line width period of the polarizer, and partial performance of the polarizer better than commercial polarizers. |
