Measured (solid lines) and simulated (dashed lines) PHEOD solitons with different dispersion. a Pure-quartic soliton spectra when taking β4 as -1.596 ps4 (yellow), –2.66 ps4 (orange), –5.32 ps4 (dark blue). b Pure-sextic soliton spectra when taking β6 as –1.33 ps6 (light blue), –2.128 ps6 (light green), –4.256 ps6 (purple). c Pure-octic soliton spectra when taking β8 as –1.064 ps8 (dark green), –2.128 ps8 (magenta blue), –3.99 ps8 (red). d Pure-decic soliton spectra when taking β10 as –1.064 ps10 (dark blue), –2.128 ps10 (light purple), –3.99 ps10 (light green). The colored circles, cross, and asterisks show the kth power of the sideband positions versus sideband order of the (e) pure-quartic, (f) pure-sextic, (g) pure-octic, and (h) pure-decic soliton spectra, solid lines correspond to a linear fit, the legend provides the calculated βk
