“…To address this issue, we proposed an efficient phase and polarization modulation method based on a single phase-only LCOS SLM to simultaneously control both the holographic image and its polarization state. In [27], we considered the zero-order noise issue caused by the pixelated structure of LCOS devices to achieve the feasibility and flexibility of a compact system for the phase and polarization modulation of light. In this paper, we demonstrated the detailed methods of a compact system for the phase and polarization modulation using based on a single LCOS SLM.…”

The technology of five-dimensional (5D) optical data storage in transparent materials paves a promising way to unlimited lifetime data storage for future cloud use. Phase-only liquid-crystal-on-silicon spatial light modulators (LCOS SLMs) have already exhibited its potential for this application in tailoring ultrafast laser writing beams for 5D optical data storage. A phase-only LCOS SLM can generate arbitrary data patterns by using diffractive holographic imaging for data writing light beam generation. However, the polarization control of the output holographic image is still achieved by using an external polarization modulator, which leads to complications, bulkiness, and large delays in current methods. In this paper, we presented an efficient phase and polarization modulation method through a compact system based on a single phase-only LCOS SLM to simultaneously control both the holographic image and its polarization state. The proposed method utilizes two-polarization-component coding in conjunction with a polarization component rotation technique in a compact system. Using this polarization rotation technique, two light components can be independently coded by separately using two holograms on two halves of the LCOS SLM. We experimentally construct a proof-of-concept prototype of the compact system, and the effectiveness of the system has been experimentally verified.

Metasurface with metal-insulator-metal (MIM) structure has absorption properties for incident light at specific wavelengths. In this paper, we propose an infrared metasurface absorber based on silicon-based complementary metal oxide semiconductor (CMOS) process. By adding the prepared infrared metasurface absorber to the liquid crystal on silicon (LCoS) chip, it is used as the absorbing layer of LCoS configured between the pixel unit and the CMOS driver circuit. The effect of zero-order light caused by the gap between pixels in LCoS spatial light modulator (LCoS-SLM) on the light modulation function of the device is effectively reduced. Experiments show that the LCoS-SLM with infrared metasurface absorption structure can eliminate the zero-order light interference between the pixel gaps to a great extent and improve the modulation efficiency of the device. The proposed LCoS-SLM integrating infrared metasurface absorber structure based on silicon-based CMOS process has the advantages of low-cost and high modulation efficiency, which has high application value in the fields of holographic display, optical computing and optical communication.
