The Convergence of Terahertz Technology and Spintronics: Pioneering Ultrafast THz Sources

The electromagnetic spectrum’s terahertz (THz) range—bridging microwaves and infrared—has long tantalized scientists with its potential for transformative applications in imaging, communication, and material science. Yet, unlocking this potential has hinged on overcoming a critical bottleneck: the lack of efficient, compact, and broadband THz sources. Enter spintronics, the field that exploits electron spin rather than charge….
