Terahertz Distributed Sensing Platform Based on Waveguide Bragg Gratings – Year two

Distributed sensing is an advanced technology that enables real-time monitoring of variations along the entire length of a waveguide, and offers the possibility of sensing from a long distance. In the optics domain, distributed sensing based on optical fibers has been successfully demonstrated. However, the realization of distributed sensing in the terahertz domain is still at an embryonal stage. This project aims at introducing the concept of distributed sensing into the terahertz domain, and developing, for the first time to our knowledge, a prototype of novel terahertz distributed sensing platform by integrating multiple THz Bragg grating sensing units into a low-loss and high coupling-efficiency THz two-wire waveguide.
