Chirped FBGs are fiber Bragg gratings with a variable period lengthwise. Fiber Bragg Gratings (FBGs) are one of the most popular technology within fiber-optic sensors, and they allow the measurement of mechanical, thermal, and physical parameters. In recent years, a strong emphasis has been placed on the fabrication and application of chirped FBGs (CFBGs), which are. Among the various innovations in fiber optics, Chirped Fiber Bragg Grating (CFBG) has emerged as a highly effective solution for wavelength filtering in optical communication systems and advanced sensing applications. Each grating is designed to reflect twelve channels.
