“…Our group theoretically studied the operation of polarization-and group-velocity-locked vector solitons with different pulse shapes, such as super-Gaussian pulse shapes [36] and bright-dark pulse pairs [37]. Moreso, theoretical investigations about operating vector bisolitons were conducted [38,39]. In this work, we further explore the operation of vector solitons with chirped sech pulse shapes, which have not been reported until now.…”

In this paper, we report the theoretical results about operating vector solitons with chirped sech pulse shapes. In the operation, the shapes of temporal pulses and corresponding optical spectra in orthogonal directions will change, which are based on soliton parameters. When input orthogonal pulses have the same central wavelength of 1064 nm, the shift from the central wavelength always occurs for orthogonal pulses. When input orthogonal pulses have different central wavelengths of 1063 nm and 1065 nm, output pulse shapes and optical spectra with obvious multiple peak/dip structures can be achieved in orthogonal directions. Our theoretical results are meaningful for the study of vector soliton dynamics and have potential applications in optical communication and optical sensing.

“…In recent years, vector optical fields have attracted significant attention due to their unique properties and wide-ranging applications in various areas, including optical communications [1], imaging [2], and beam manipulation. These vector fields can possess characteristics such as complex spatial structures, nonuniform polarization distribution [3], and novel phase distributions [4], providing a new way to precisely manipulate light [5]. The concept of phase modulation in vector optical fields originates from the study of wave optics and optical phase engineering.…”

This study investigates the influence of high-order twisting phases on polarization states and optical angular momentum of a vector light field with locally linear polarization and a hybrid state of polarization (SoP). The twisted vector optical field (TVOF) is experimentally generated based on the orthogonal polarization bases with high-order twisting phases. The initial SoP of a TVOF modulated by the high-order twisting phase possesses various symmetric distributions. The propagation properties of a high-order TVOF with locally linear polarization and hybrid SoP are explored, including the intensity compression, expansion, and conversion between the linear and circular polarization components. In particular, orbital angular momentum (OAM) appears in a high-order TVOF during propagation where no OAM exists in the initial field. The variation of OAM distribution in cross-section becomes more frequent with the increase of the twisting phase order. In addition, a non-symmetric OAM distribution appears in a non-isotropic TVOF, leading to the rotation of the beam around the propagation axis during propagation. The optical energy flow distribution of a high-order TVOF provides a more profound understanding of the propagation dynamics of high-order TVOF. These results provide a new approach for optical field manipulation in a high-order TVOF.

“…[19] We theoretically investigated the out-cavity manipulation of Yb-doped fiber laser VSs with various pulse properties, which include super-Gaussian pulses, [20] dark-dark pulses, [21] bright-dark pulses, [22] self-similar pulses, [23] selfsimilar vector bisolitons, [24] and so on. [25][26][27][28] Through varying soliton pulse parameters in orthogonal directions, finally, various kinds of pulse shapes and optical spectra in output orthogonal directions were got. But there have been few reports about super-sech VS pulses' modulation.…”

Theoretical simulations about manipulating vector solitons with super-sech pulse shapes are conducted based on an optical fiber system in this manuscript. By changing temporal pulses’ parameters when orthogonally polarized pulses have the same or different input central wavelengths, output modes in orthogonal directions will demonstrate different properties. When input orthogonal modes have the same central wavelength, “2+2” pseudo-high-order vector soliton can be generated when time delay is changed. While under the condition of different central wavelengths, orthogonal pulses with multiple peaks accompanied with two wavelengths can be achieved through varying projection angle, time delay or phase difference. Our simulations are helpful to the study of optical soliton dynamics in optical fiber system.
