| Summary: | This study proposes a transparent conductive thin film microstructure capable of effectively modulating the optical properties of the film. Simulation results show that grating-structured indium tin oxide (ITO) films can modulate the surface electric field distribution by adjusting the structural parameters of the grating. This modulation enables a strong electric field to extend to the air side without compromising the integrity of the transparent conductive layer, thereby enhancing resistance to laser-induced damage. Increasing the grating period from 336 nm to 408 nm shifts the surface plasmon resonance wavelength from 506 nm to 600 nm. Therefore, the period of ITO grating exhibits the characteristic of wavelength selection. The optical properties of ITO gratings are also sensitive to film thickness and filling factor. Simulations of other microstructures confirm similar modulation effects. These results provide a theoretical basis for the design and preparation of transparent conductive thin films that meet the demands of high-power, high-throughput liquid crystal optical devices. |
