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. WebThe RTL implementation was done in Verilog. The adder was changed into kogge-stone adder [2] to improve the performance of the custom chips. The previous bugs were also fixed and new feature to overlap FFT/IFFT computation was also introduced in the form of next_data signal.
