On-chip broadband high-resolution digital Fourier transform spectrometer

In this project, Brian Neltner designed and assembled a high resolution amplifier and sensor for setting heater voltages and measuring photocurrents in order to measure the light intensity reaching a single photodiode for each binary combination of heaters. Maarten’s algorithm was able to then convert this discrete data for each heater voltage combination to calculate the overall spectrogram.
