High-capacity optical fiber transmission systems are the backbone of modern telecommunication networks. The research activity focuses on both long-haul systems and local-area networks.
Optical fibers can act as sensors, because they are intrinsically sensitive to (among the others) temperature, strain and magnetic fields. Beside enabling the multiplexing of several tens of discrete sensors, optical fibers sensors have the unique ability of performing distributed monitoring, where the physical field under analysis can be measured over the entire length of the fiber (up to several kilometers) with spatial resolution ranging from few centimeters to few meters The research activity covers the following topics:
Nonlinear effects in optical fibers enable several kind of all-optical signal processing, ranging from amplification to filtering. In particular, the research activity focuses on the following topics:
Polarization-sensitive optical coherence tomography (PS-OCT) is an imaging technique that allows non-invasive in-depth imaging of biological specimens. In particular, the sensitivity to polarization allows to increase the imaging contrast of specific tissues, like muscles; moreover, the optical-fiber implementation of PS-OCT is particularly robust and versatile. The topics covered by the research activity are the following:
