Solution-processable materials are becoming increasingly attractive due to their use in low cost, high throughput and relatively easy fabrications. In addition, the possibility of high-resolution patterning makes solution-based materials particularly suitable for integrated applications. The material that was investigated in this work is zinc oxide nanoparticles (ZnO NPs) dispersion, motivated by the highest resolution on record of optically addressed spatial light modulators (OASLMs) using solution-based ZnO NP as photoactive material. ZnO is a popular type of semiconductor compound from II-VI group and ZnO NPs are the nanocrystalline form of ZnO, which exhibit many unique and superior properties such as direct and wide bandgap, large surface-to-volume ratio, antibacterial and eco-friendly nature. Therefore, the investigation of ZnO NPs in terms of their physical properties, post processing effect, patterning techniques, and applications are of great significance. In this work, thin films made from ZnO NP dispersion in ethanol was characterized in detail including their structural, electrical, dielectric and optical properties. The post-processing effect such as thermal annealing and oxygen plasma treatment was also investigated. Then ZnO NP-based OASLM was researched by simulation and device characterization regarding electrical and optical properties. More importantly, the optimization of ZnO NP-based OASLMs was conducted in terms of diffraction efficiency and response speed, which are two key factors limiting the development of ZnO NP-based OASLMs. The diffraction efficiency was improved by pinpointing the optimum parameters of the driving signal such as waveform, amplitude and frequency. And the response time was reduced by several methods such as thermal annealing, introducing an interfacial layer and replacing the photoconductive ZnO NP layer with ZnO NP-based photodiode structure. The sensing of oxygen partial pressure in air by ZnO NP thin film was also obs

Terahertz (THz) technology offers unparalleled opportunities in a wide variety of applications, ranging from imaging and spectroscopy to communications and quality control, where lack of efficient modulation devices poses a major bottleneck. spatial modulation allows for dynamically encoding various spatial information into the THz wavefront by electrical or optical control. It plays a key role in single-pixel imaging, beam scanning and wavefront shaping. Although mature techniques from the microwave and optical band are not readily applicable when scaled to the THz band, the rise of metasurfaces and the advance of new materials do inspire new possibilities. In this review, we summarize the recent progress of THz spatial light modulators from the perspective of functional materials and analyze their modulation principles, specifications, applications and possible challenges. We envision new advances of this technique in the near future to promote THz applications in different fields.

We have developed a magneto-optical spatial light modulator (MO-SLM) with a 10 k x 5 k pixel layout and with a pixel pitch horizontally of 1 & mu;m and vertically of 4 & mu;m. An MO-SLM device pixel has a magnetic nanowire made of Gd-Fe magneto-optical material whose magnetization was reversed by current-induced magnetic domain wall motion. We successfully demonstrated the reconstruction of holographic images, showing large viewing zone angles as wide as 30 degrees and visualizing different depths of the objects. These characteristics are unique to holographic images, providing physiological depth cues which may play a vital role in three-dimensional (3D) perception.& COPY;2023 Optica Publishing Group under the terms of the Optica Open Access Publishing Agreement

Advances in consumer display screen technologies have historically been adapted by researchers across the fields of optics as they can be used as electronically controlled spatial light modulators (SLMs) for a variety of uses. The performance characteristics of such SLM devices based on liquid crystal (LC) and digital micromirror device (DMD) technologies, in particular, has developed to the point where they are compatible with increasingly sensitive instrumental applications, for example, Raman spectroscopy. spatial light modulators provide additional flexibility, from modulation of the laser excitation (including multiple laser foci patterns), manipulation of microscopic samples (optical trapping), or selection of sampling volume (adaptive optics or spatially offset Raman spectroscopy), to modulation in the spectral domain for high-resolution spectral filtering or multiplexed/compressive fast detection. Here, we introduce the benefits of different SLM devices as a part of Raman instrumentation and provide a variety of recent example applications which have benefited from their incorporation into a Raman system.

High performance electrically-derived single-pixel magnetophotonic spatial light modulator

JOURNAL OF MAGNETISM AND MAGNETIC MATERIALS 2024年 599卷

spatial light modulators (SLMs) utilize components such as magnetophotonic crystals (MPCs) to alter specific characteristics of a light beam in space. In magneto-optical (MO) spatial light modulators, MPCs play a crucial role in spatially modulating light by manipulating local light intensity and polarization rotation. This study explores how the refractive indices of birefringent electro-optical materials within MPCs influence MO rotation and reflection. In this order, using a transfer matrix method, we designed thin MPCs with a MO rotation around 90 degrees and almost full reflection, for having SLMs with high contrast. The direction of applied voltage to the structure was found to be a critical factor, leading to significant reduction in power consumption for SLMs incorporating the MPCs. These characteristics render the designed MO spatial light modulator well-suited for applications in projectors and displays.

spatial light modulators (SLMs), which control the amplitude, phase, and polarization of light are the core components of many optical applications. Integrating graphene with dielectric metasurfaces supporting quasi-bound states in the continuum (quasi-BIC) offers potential advantages of low energy consumption, high speed, and small size of modulators. In this paper, we propose a modulator with a 2 pi phase shift, by transforming the coupled system from an underdamped resonator to an overdamped one by tuning the Fermi level of graphene through simulation. Additionally, we demonstrate the application of this device in one-bit programmed holography. The proposed modulator with its combined advantages of low power consumption and compact footprint, enables fruitful applications in holographic display, beam steering in light detection, ranging and biomedical imaging systems.
