Abstract We simulate the polarization manipulation of bright-dark vector bisolitons at 1-μ m wavelength regime. Through changing the pulse parameters, different kinds of pulse shapes and optical spectra are generated in output orthogonal polarization directions. When the input vector bisoliton is polarization-locked with 1064 nm central wavelength, "1+1" fundamental dark-dark and "2+1" pseudo-high-order bright-dark group-velocity-locked vector solitons can be achieved through changing the projection angle. When the input vector bisoliton is group-velocity-locked with 1063 nm and 1065 nm central wavelengths, "2+1" and "2+2" pseudo-high-order bright-dark group-velocity-locked vector solitons, bright-dark group-velocity-locked vector solitons with chirp-like temporal oscillations are generated. Our simulation results can provide beneficial conduct for polarization manipulation of vector multi-solitons, and have promising applications in quantum information register, optical communications, nanophotonics, and all-optical switching.

Altmetric calculates a score based on the online attention an article receives. Each coloured thread in the circle represents a different type of online attention. The number in the centre is the Altmetric score. Social media and mainstream news media are the main sources that calculate the score. Reference managers such as Mendeley are also tracked but do not contribute to the score. Older articles often score higher because they have had more time to get noticed. To account for this, Altmetric has included the context data for other articles of a similar age.
