AB - Addressed Fiber Bragg Structures (AFBS) serve a dual purpose, acting as complex-sensitive elements with two distinct configurations: one involving two Fiber Bragg Gratings (2λ-AFBS) with different Bragg frequencies, and the other employing a single FBG with two π-phase shifts (2π-AFBS). The difference frequency between these configurations acts as the unique AFBS address, which remains constant regardless of the measured physical fields. Additionally, they function as a two-frequency laser radiation source capable of operating in both reflection and transmission modes, corresponding to the structure above. When the difference frequency is unique for each AFBS, it enables self-multiplexing of sensors. In this article, we present the ontology of AFBS, encompassing parent structures with 2λ- or 2π-components and their successor AFBS with three spectral components. These structures offer various combinations of difference frequencies, both symmetrical and asymmetric, allowing them to address and convert information signals to the low-frequency range while also mitigating collisions caused by the relative shifts of structures’ spectra during measurements. We also explore the subjects of interrogation for these structures and discuss their calibration, as well as the future prospects of AFBS development, including the usage of hybrid AFBS.
