Fiber Bragg Grating (FBG) is significantly affected by external pressure, which alters the grating period and consequently the reflected wavelength. The relationship between pressure and wavelength shift is critical for applications in sensing technology. For further reading, refer to "Fiber Bragg Grating Sensors" by A. K. G. S. S. S. R. S. Kumar, which provides in-depth analysis and experimental results on this topic.
