INFLUENCE OF TEMPERATURE ON THE PARAMETERS OF TRANSVERSE BRAGG GRATINGS

The presented article states that various control methods based on optical technologies are currently relevant and are used in areas other than engineering and science. It is said that there is interest in Bragg gratings, including oblique Bragg gratings. The history of the oblique Bragg grating is briefly discussed, and its definition is given. Focusing on their features, the main formulas were reviewed in detail. Brief details of the conducted research are given, and data on experiments performed in certain temperature ranges are given. Sets of spectral characteristics are given, and graphs of temperature dependence of Bragg and host wavelengths of OBG are given. At the same time, the temperature sensitivity and coefficients of OBG were calculated and the results were presented in the form of a table.
