Metasurface-based beam splitters with broadband and high efficiency are highly desirable in various optical and photonic applications. In this paper, we theoretically propose a switchable equal power beam splitter with large beam splitting angle based on a continuous metasurface by integrating the vanadium dioxide (VO2). Utilizing the phase change characteristics of VO2, the beam splitter can be thermally switched between transmission and reflection modes in the near-infrared region. Moreover, the theoretical calculation value of the splitting angle matches well with the simulation result. And the conversion efficiencies of both transmission and reflection modes reach up to ∼100% in a broadband wavelength range. In addition, we discuss the influences of related geometrical parameters on the performance of beam splitter in detail. Our proposed switchable power beam splitter may have potential applications in integration and miniaturization of modern optical devices.
