Open access Nature Communications paper : https://www.nature.com/articles/s41467-018-06773-2 https://www.nature.com/articles/s41467-018-06773-2 High-performance and scalable on-chip digital Fourier transform spectroscopy Here we demonstrate a transformative on-chip digital Fourier transform spectrometer that acquires high-resolution spectra via time-domain modulation of a reconfigurable Mach-Zehnder interferometer. The device, fabricated and packaged using industry-standard silicon photonics technology, claims the multiplex advantage to dramatically boost the signal-to-noise ratio and unprecedented scalability capable of addressing exponentially increasing numbers of spectral channels.
