Line Plot from Scientific Research

Reconstruction results of a response of a fiber Bragg grating (FBG). The reference and reconstructed spectra are shaded in red and blue, respectively. The reference spectra were measured using a commercial optical spectrum analyzer (OSA), while the reconstructed spectra are derived from the measured interferograms (see Supplementary information, Note 9 , Figs. S19 and S20 ). The relative errors ( ) and coefficients of determination ( r 2 ) are also labeled. In Fig. 5c, d, the dashed lines show the intensity levels of 35 dB and 25 dB, respectively.
