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...

Optical Switch

Optical Switch Conventional Wavelength Selective Switches (WSSs) steer light in one dimension. This fundamentally limits the number of output ports. A typical WSS has one input fibre, and multiple output fibres. Light is launched into free space from the input fibre, at the centre of a linear fibre...

Transparent Conductors(TC) for Middle Infrared(Mid-IR) Liquid Crystal Spatial Light Modulators (LC-SLM)

Transparent Conductors(TC) for Middle Infrared(Mid-IR) Liquid Crystal Spatial Light Modulators (LC-SLM) In the Mid-IR(λ = 2 to 5 μm) range, LC-SLMs can offer a low-cost, non-mechanical and compact alternative to the gimbaled mirrors used currently for Mid-IR laser beam-steering. Unfortunately...

A High-Resolution Optically Addressed Spatial Light Modulator Based on ZnO Nanoparticles

A High-Resolution Optically Addressed Spatial Light Modulator Based on ZnO Nanoparticles An optically addressed spatial light modulator (OASLM) can modulate the wavefront of a read light by displaying a phase pattern or a hologram configured by the intensity distribution of a write light. Using ZnO...
