In this paper, we introduce a distributed fiber optic sensing approach for crack monitoring along concrete tunnel linings. The designed setup allows strain measurements with a very high precision of about 1µm/m every 10 millimeters or even better.

What is the value of silicon photonics technology
In a typical optical link, data is first transferred from the electrical to the optical domain using an or a directly modulated laser. An electro-optic modulator can vary the intensity and/or the phase of the optical carrier.
