  • Digital Fourier Transform (dFT) spectroscopy: we pioneered a new on-chip spectrometer architecture enabling exceptional optical performance within a small chip-scale footprint. We also developed a machine-learning spectrum reconstruction algorithm that enhances spectral resolution well beyond the classical Rayleigh criterion.    Read more | MIT News
