Modulating vector soliton molecules

We theoretically modulate vector soliton molecules in an optical fiber system model, when input orthogonal modes’ central wavelengths are the same or different. In the case of same central wavelength with 1064 nm, output orthogonal modes maintain their states in time or frequency domain, when projection angle or phase difference changes. While when orthogonal components have slightly different central wavelengths (2 nm wavelength difference), energy flow occurs when projection angle varies. Our results are applicable to polarization-multiplexed optical fiber communication, ultrafast optical fiber laser and so on.
