Ultrafast Spectrogram with Sub-THz Bandwidth

We demonstrate a photonics-based spectrogram with an operation bandwidth of 380 GHz and a time resolution of 62.5 ps. This proposed linear-optics based scheme allows for the analysis of highly sophisticated waveforms, here shown on a sub-THz signal with a time-bandwidth product of ~1,826.
