We explore our results for applications in fields such as spintronics (e.g., the ultrafast control of magnetic bits) and terahertz photonics. Here, the development of new emitters and detectors of terahertz radiation plays an important role since the terahertz range is still relatively difficult to access.

• For example, we used the spintronic structure of Figure 2 above to develop a novel emitter of terahertz radiation that is more efficient and broadband than established emitters. The short movie gives a preview of spintronic terahertz emitters at work in the lab.
• Recently, we were able to reverse the concept of Figure 2 and, thus, develop a detector of ultrabroadband terahertz electric fields.
