Multi-layer Metal-mesh THz Filters

Recent advances in ultrafast lasers and electronics have made terahertz (THz) radiation systems possible that, while still emerging, have shown important benefits for medicine, security and defense, food safety, non-destructive testing in manufacturing, and scientific research. Tera Hertz frequencies are also a leading contender for the next generation wireless communications network (i.e., “6G”) due to their ability to transmit data 5 to 50 times faster than current 5G networks. An important element of many THz systems are THz bandpass filters that allow direct control of the frequencies that are either emitted or absorbed by THz filters sources and detectors.

To address this need, we are developing a rapid, low-cost manufacturing capability for THz filters based on our proprietary nano-ablation process. This approach allows us to eliminate slow and expensive photolithography-based fabrication steps and use lower-cost, high-performance starting materials. We are also developing an automated process for designing custom filters to enable rapid delivery of custom, low-cost THz filters.
