Scatter Plot from Scientific Research

Reconstruction results of a response of a single channel of an arrayed waveguide grating (AWG). 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.
