The unique in-plane and out-of-plane anisotropy of α-MoO3 has attracted considerable interest with regard to poten-tial optoelectronic applications.However,most research has focused on the mid-infrared spectrum,leaving its properties and applications in the visible and near-infrared light spectrum less explored.This study advances the understanding of waveguiding properties of α-MoO3 by near-field imaging of the waveguide modes along the[100]and[001]directions ofα-MoO3 flakes at 633 nm and 785 nm.We investigate the effects of flake thickness and documented the modes'dispersion relationships,which is crucial for tailoring the optical responses of α-MoO3 in device applications.Our findings enhance the field of research into α-MoO3,highlighting its utility in fabricating next-generation optoelectronic devices due to its unique optically anisotropic waveguide.
