Abstract

Pure-high-even-order dispersion (PHEOD) solitons emerge from the balance between negative high-even-order dispersion and the self-phase modulation, manifesting as pulses with significantly enhanced peak power and flattened spectrum envelope. In contrast to conventional solitons dominated by second-order dispersion, the unique features of PHOED solitons have attracted significant attention. Here we theoretically investigate a soliton-order modulation method in passive driven fiber resonators based on Panda-Photonic Crystal Fiber (Panda-PCF). The transition of soliton orders corresponding to the two polarization directions in Panda-PCFs is achieved by controlling the polarization of pump source. Besides, we investigate the anisotropic helically twisted Panda-PCF for the generation of orbital angular momentum (OAM) modes, achieving stable spatio-temporal cavity soliton transmission. Our work might benefit the investigation of cavity solitons and OAM mode regulation.
