Description

The design of devices capable of guiding light over long distances is of current interest in Optics, especially for Telecommunication applications. The implementation of fiber optic devices with periodic refractive index changes is achieved via modulation of the cores refractive index. This fixed modulation in the refractive index is called grating, which reflects a fixed wavelength, known as the Bragg wavelength. Since such devices show interesting spectral characteristics, they have found many applications in areas such as: instrumentation in single point and distributed sensors, in applications where sensing mechanical changes is key as in Structural Health Monitoring applications[1,2], in temperature and even in pH sensors[3]. Nonetheless, in optical communications as signal filters or as dispersion compensators[4], and as demultiplexer devices and many other applications as the ones shown in Fig.1, taken from T. Guo et.al [5]
