Abstract: We designed and experimentally demonstrated an on-chip Fourier transform spectrometer on silicon-on-sapphire. The spectrometer comprises an array of twelve Mach–Zehnder interferometers (MZIs) with linearly increasing optical path delays between MZI arms. The propagation loss of… read more here.
