Here, we investigate the plasmonic modes in twisted bilayer 2D materials (e.g., black phosphorous). Calculated dispersion curves show that two hyperbolas split as the twisted angle increases. The topological transition from closed ellipses to open hyperbolas is achieved by varying the frequency, indicating switching between highly directional and omnidirectional plasmons. These findings will provide potential applications of anisotropic 2D materials in the design of tunable field effect transistors and waveguides.||URI:||https://hdl.handle.net/10356/141871||ISSN:||0146-9592||DOI:||10.1364/OL.43.005737||Rights:||© 2018 Optical Society of America.
