Microwave photonic polyharmonic processes for fiber-optical structures of telecommunication systems probing

The development of the technology of fiber-optic sensors is inextricably linked with the development of the technology of fiber-optic telecommunication systems (FOTS). The increased capabilities of telecommunication technologies allow the creation of spatially spaced and multidimensional sensor networks. On the other hand, the development of sensor technologies, in turn, allows the creation of highly efficient monitoring systems for telecommunications networks, in particular their selective elements, which include wave etalons, add/drop multiplexers, thin-film filters, arrayed waveguide gratings, widely used Fiber Bragg gratings (FBG), etc.
