Graphical overview of electrical-domain fiber-optic sensing.

Caption

This image summarizes the newly demonstrated sensing principle. Light transmitted through a single-mode fiber (SMF)–polymer optical fiber (POF)–SMF structure is photodetected, and interference dips appearing in the electrical spectrum are tracked to detect strain. The same principle can also be extended to displacement sensing using an air-gap structure between silica fibers.
