A polarization-dependent microknot resonator(MKR) functions as comb filter and accounts for the narrow linewidth(0.018 nm) of multiwavelength channels. The wavelength interval corresponds to the free spectral range of the MKR. We exploit a fused SMF–FMF(single mode fiber–few mode fiber) mode coupler to obtain broadband mode conversion and successfully achieve multiwavelength switchable OVBs. As far as we know, this is the first report about identical multiwavelength vortex beams with topological charges of 1. It has been verified that each channel of the vortex beams preserves the same orbital angular momentum(OAM) properties through their clear spiral interferograms. Multiwavelength vortex beams with identical OAM properties are desirable for multiplexing, exchanging, and routing to further improve the capacity of optical fiber transmission. 关 键 词：OAM Wavelength-switchable vortex beams based on a polarization-dependent microknot resonator
