The article investigates photonic crystal fibers (PCFs) with triangular and kagome structures for use in fiber optic gyroscopes (FOGs). The advantages of PCFs in enhancing FOG performance are substantiated, highlighting their unique features, such as high sensitivity, low optical losses, and resistance to temperature fluctuations. Mechanisms of energy localization through photonic bandgaps and single-mode operation are discussed to improve measurement accuracy. Numerical calculations of dispersion characteristics and eigenmodes of PCFs were performed using the plane wave expansion method in the MIT Photonic Bands software. The modal properties of various PCF designs were analyzed, focusing on the impact of hollow core diameter on spectral characteristics. It is demonstrated that the optimal ratio of geometric parameters ensures effective energy localization in the hollow core and minimizes losses.Special attention is given to PCFs with kagome lattices, which show potential for reducing energy losses due to the spatial distribution of the electromagnetic field. Conclusions are drawn about the application of PCFs in gyroscopes for aviation and defense navigation systems. The findings open new possibilities for developing high-precision equipment capable of operating under extreme conditions.
