| Popis: | A novel way to generate asymmetric optical comb sources is presented. Optical comb sources are an essential component of Terabit orthogonal frequency-division multiplexing (OFDM) and wavelength division multiplexing-Nyquist (WDM-Nyquist) systems. Each arm of the modulator is excited with the linear combination of two sine waves. An asymmetric output spectrum characterized by a flat region, where spectral ripple less than 1dB and which width ranges from 4 to 32 sub-carriers. The simulated annealing optimization algorithm was used to speed up the search for the aforementioned flat regions. The search results for the entire possibility space are interpolated. |
