Terahertz photonics

Terahertz photonics studies the use of light waves in the terahertz frequency range—between microwaves and infrared light—to generate, detect, and manipulate signals. These waves can probe materials deeply, enabling applications like high-resolution imaging, advanced spectroscopy, and secure wireless communication. Terahertz photonics combines optical and electronic technologies to develop devices that operate efficiently at these frequencies, unlocking new capabilities in medicine, security, and communication systems. Essentially, it harnesses a part of the electromagnetic spectrum that offers unique insights and functionalities beyond traditional RF or optical methods.
