Fibre optic sensors (FOSs) are nowadays widely adopted in structural health monitoring (SHM) of mechanical and aeronautical components thanks to their high sensitivity, reduced size, electro-magnetic immunity, and ease of being embedded in composite materials, enabling the realization of smart structures. SHM refers to the identification of damages due to both fatigue loads and impact occurrence....
A novel distributed fiber-optic vibration sensor is proposed and experimentally demonstrated. The sensor relies on a dual Mach-Zehnder ring interferometric architecture associated to a new coherent detection scheme, borrowed from high bit rate coherent optical communications, which performs a completely passive management of polarization and phase variables of the received optical signal. The proposed...
We present a compact (< 0.65 mm2) silicon photonics variable-delay receiver for DPSK optical transmission systems consisting of a Mach–Zehnder interferometer (MZI) loaded with an integrated tunable delay line. The delay line is realized by using a thermally actuated coupled-resonator optical waveguide (CROW) in reflective configuration, providing a continuous control of the MZI delay from 66 to...
