Abstract

A compact on-chip Fourier transform spectrometer based on the Mach-Zehnder interferometer (MZI) array is proposed. The experimental results show the silicon-on-insulator (SOI) based spectrometer can reconstruct narrowband signals with full width at half maximum (FWHM) of 0.5 nm and a triplex-peak signal separated by 3-nm distance with the assistance of the pattern coupled sparse Bayesian learning (PCSBL) reconstruction algorithm.
