WebWe report the design of an all-optical fast Fourier transform (FFT) on a silicon-photonics on-chip platform, show the phase-, amplitude-, and delay sensitivity of the transfer function, and a delay performance of 20 Tbps. A fast Fourier transform (FFT) is an algorithm that computes the discrete Fourier transform (DFT) of a sequence, or its inverse (IDFT). Fourier analysis converts a signal from its original domain (often time or space) to a representation in the frequency domain and vice versa.
