Abstract
Combining multiple physical fields to achieve on-demand signal conversion is essential. Optical manipulation based on holography, especially electric field-driven holography, can promote efficient information processing. However, there is a lack of a platform that can effectively connect optical recording/reading with electric field. Herein, we construct a photoelectrochemical reaction system with the metal ions sandwiched in TiO2/FTO electrodes, which exhibits voltage-controlled holographic plasticity. The hysteresis of ion balance under photoelectric activation leads to switchable long-/short-term hologram memory with light intensity dependence. The enhancement of holographic visual information can be achieved through periodic electrical stimulation. This work provides a potential platform for optoelectrical memory devices and dynamic holographic displays.
期刊介绍：
The Optical Society (OSA) publishes high-quality, peer-reviewed articles in its portfolio of journals, which serve the full breadth of the optics and photonics community.
Optics Letters offers rapid dissemination of new results in all areas of optics with short, original, peer-reviewed communications. Optics Letters covers the latest research in optical science, including optical measurements, optical components and devices, atmospheric optics, biomedical optics, Fourier optics, integrated optics, optical processing, optoelectronics, lasers, nonlinear optics, optical storage and holography, optical coherence, polarization, quantum electronics, ultrafast optical phenomena, photonic crystals, and fiber optics. Criteria used in determining acceptability of contributions include newsworthiness to a substantial part of the optics community and the effect of rapid publication on the research of others. This journal, published twice each month, is where readers look for the latest discoveries in optics.
