The linear electro-optic effect offers a valuable means to control light properties via an external electric field. Lithium niobate (LN), with its high electro-optic coefficients and broad optical transparency ranges, stands out as a prominent material for efficient electro-optic modulators. The recent advent of lithium niobate-on-insulator (LNOI) wafers has sparked renewed interest in LN for compact photonic devices.

- Electrically reconfigurable nonlinear metasurfaces allow for dynamic control of second-harmonic generation (SHG), leading to innovative uses in signal processing, light switching, and sensing.
- Traditional methods have limitations due to weak SHG responses in metals and constraints in quantum well systems.
- A new approach using lithium niobate (LN) combines the electro-optic effect with SHG, achieving an 11.3% modulation depth, which enhances the potential for tunable nonlinear light sources and advanced photonic applications.
Polarimeters, which measure the polarization states of light directly, are essentially desired in many areas of science and technology. In our previous work, we have constructed a polarimeter based on a rotating-metasurface, and the polarization Stokes parameters of the light were measured with the known Mueller elements of the metasurface. Here, we further perform the error analysis of the metasurface polarimeter.
