In this paper, a monolithic silicon carbide (SiC) metalens with excellent thermal stability is introduced. We propose a Particle Swarm Optimisation (PSO)-based Wide-Temperature Phase Stabilisation (PSO-WTPS) strategy to optimise model parameters. This approach compensates for phase drift induced by temperature-dependent refractive index variations and thermal expansion, thereby suppressing the degradation of the metalens’ operational performance at elevated temperatures. Simulations indicate that over the temperature range from 300 K to 1273 K, the drift in the collimation divergence angle of the metalens remains below 0.13 mrad, while the transmittance exceeds 75%.

The second degree of freedom is provided by the phase-change-induced conductivity variation of VO₂, allowing active tuning of the chiral response during its insulator-to-metal transition. Under linearly polarized terahertz wave incidence, the polarization state of the reflected wave is modulated via the combined control of the incident angle and the phase transition state of VO₂.

At this incident angle, the device satisfies the amplitude and phase conditions required for circular polarization generation, enabling continuous evolution of the reflected polarization state on the Poincaré sphere through the joint tuning of the angle and phase transition.
