The concept of cascaded micro-ring four-wave mixing (FWM) as a signal processing technique involves using a series of interconnected micro-rings to mix four distinct optical frequencies. This implementation leverages the Fast Fourier Transform (FFT) algorithm for efficient computation of the resulting mixed signal spectrum, where the FFT handles frequency domain transformations and convolution operations. The algorithm processes input signals through discrete Fourier transformations to model the nonlinear interactions within the micro-ring resonators. This method has been successfully implemented and tested in the MATLAB 2013b environment, using built-in functions like fft() and ifft() for spectral analysis and signal reconstruction. The code structure includes modules for micro-ring parameter configuration, FWM efficiency calculation, and spectral visualization, demonstrating practical applications in telecommunications and digital signal processing systems.
