The system utilizes arrayed of fiber delay lines (FDL) to passively generate sub-carrier signals and offers simultaneous plotting of multiple optical spectra. Accurate recovery of individual spectrum of multiplexed long period gratings spectra is experimentally demonstrated in a refractive index sensing application. The accuracy achieved is outstanding with a value of coefficient of determination, R2 between pristine and demultiplexed signals of at least 98.98%. The proposed technique offers economical and efficient system costs by removing the utilization of electro-optical modulators, in addition to system scalability.
