Electrically Tunable Fano Resonances in Liquid Crystal-based Dynamic Metasurface at Telecommunication Wavelengths

15 April 2025

Electrically Tunable Fano Resonances in Liquid Crystal-based Dynamic Metasurface at Telecommunication Wavelengths Dielectric metasurface has become a versatile platform for light manipulation. Due to its subwavelength feature size, the metasurface can induce optical resonances with tailored characteristics, such as Fano...

Phase Flicker Induced Sharpness Deterioration of Holographic Images in LCoS

17 March 2025

Phase Flicker Induced Sharpness Deterioration of Holographic Images in LCoS Phase flicker in LCoS devices can decrease the effective phase modulation resolution by introducing overlapped phase oscillation between adjacent modulated grey levels, thus degrading the performance of LCoS devices in various applications...

LC Diffractive Optical Elements with High PB Phase Accuracy for Holographic Displays

17 March 2025

LC Diffractive Optical Elements with High PB Phase Accuracy for Holographic Displays Diffractive optical elements (DOE) are important light manipulating components in modern imaging and display scenarios. However, the weight of the bulk material of traditional DOEs becomes more and more critical in novel optical systems...

Adaptive Contrast Enhancement in Computer-Generated Holography Using Nonlinear Optimization

1 March 2025

Adaptive Contrast Enhancement in Computer-Generated Holography Using Nonlinear Optimization This study introduces an advanced nonlinear exponential merit function to enhance the contrast and dynamic range of computer-generated holography (CGH). By integrating adaptive energy redistribution into the Gerchberg–Saxton (GS)...
