Abstract

In this paper, we illustrate a discrete Fourier processor based on dual optical frequency combs (OFCs). The simulation verified the DFT calculation with the frequency coverage of 0.2 GHz to 3 GHz and the resolution is 200 MHz. Meanwhile, demodulation of standard OFDM signal in time domain is simulated. This scheme avoids the problem of "electronic bottleneck" in current all-electronic processors. It is superior to the existing photon-assisted Fourier transform schemes in flexibility and accuracy, and has the characteristics of low power consumption, high throughput and high precision.
