A polarization-independent metasurface optical switch based on electrochemical metallization working at 1.55 μm is proposed. The unit cell of the device comprises a silicon substrate, silica dielectric layer, and silver cross structure embedded in silica. The formation and rupture of conductive filaments between sub-units can alter the resonant wavelength of the cross structure, which triggers the state of the optical switch on or off. Numerical results demonstrate that the extinction ratio of the metasurface optical switch can exceed 14 dB at 1.55 μm, and it is insensitive to the transverse electric (TE) mode and transverse magnetic (TM) mode of light. The proposed device is expected to address the problems of high-power consumption, enabling the adoption of large-scale optical switches in optical switches, optical modulation, optical storage and computing, and large-scale photonic integrated devices.
