Pulse shaping of bright-dark vector soliton pair

We simulate pulse shaping of bright-dark vector soliton pair in an optical fiber system. Through changing input pulse parameters (amplitude ratio, projection angle, time delay, and phase difference), different kinds of pulse shapes and spectra can be generated. For input bright-dark vector soliton pair with the same central wavelength, "2+1"- and "2+2"-type pseudo-high-order bright-dark vector soliton pairs are achieved. While for the case of different central wavelengths, bright-dark vector soliton pairs with multiple pulse peaks/dips are demonstrated with appropriate pulse parameter setting.
