    Analysis of the Causes of Fiber Bragg Grating Wavelength Misalignment

    Fiber Bragg Gratings face significant angular misalignment challenges in contemporary optical systems, primarily stemming from manufacturing tolerances, installation imprecision, and operational environmental factors. These wavelength-selective devices, formed by creating periodic refractive index modulations within optical fiber cores, have revolutionized. High-temperature-resistant fiber Bragg gratings (FBGs) are the main competitors to thermocouples as sensors in applications for high temperature environments defined as being in the 600–1200 °C temperature range.
