# Special Issue on Advanced Optoelectronic Devices and Systems: An Overview
###### Abstract  
Advanced optoelectronic devices and systems are at the forefront of modern science, and their advances have led to significant advances in various industries, including telecommunications, healthcare, energy, and computing. These devices and systems play an important role in remote sensing, microscopic imaging, optical communication, and other fields, enabling high-speed communication, efficient energy conversion, precise sensing, and advanced imaging [1, 2]. But also drive or promote the development of related physical principles, sensors, and system integration research [3, 4].  
For advanced optoelectronic devices, in mid-infrared (MIR) band optical absorption regard, 2D materials are widely used in target acquisition, aerial imaging, optical communication, low-visibility imaging, and so on [5, 6]. Piezoelectric ceramic actuators have the advantages of fast response speed and high positioning accuracy. Piezoelectric positioning platform equipment with it as the core can accurately realize the micro-nano level travel requirements, so it has been widely concerned by micro-machinery, aerospace, and optoelectronic systems fields [7, 8]. However, photodetectors based on different materials have different defects. In order to solve the defects, plasma integration technology and quantum dots hybrid structures [9] can be used to improve the quality of the devices and provide methods and ideas for the subsequent realization of high-performance photodetectors. Hysteretic nonlinearity has a great influence on the positioning accuracy of piezoelectric ceramic actuators [10]. This kind of problem is difficult to model and compensate accurately, so novel modeling methods such as perturbation models can describe complex hysteresis effects [11], and advanced control algorithms such as the control strategy combining iterative learning control (ILC) and hysteresis can compensate the nonlinearity and uncertainty of the system [12], so that these problems can be solved to a certain extent. For the photoelectric system in the field of airborne remote sensing, due to the harsh environmental conditions of the airborne, the photoelectric platform is seriously interfered with by the outside world, and the high speed and height ratio under specific requirements will also cause serious image motion [13]. In order to meet the higher requirements of the airborne optoelectronic platform for visual axis stability accuracy and imaging resolution, advanced image processing technology [14] or control algorithm is usually used, such as genetic algorithm [15] and feedback-feedforward control to improve the visual axis stability accuracy and image motion compensation ability of the system to a certain extent.  
The purpose of this Special Issue, \"Advanced Optoelectronic Devices and Systems\", is to discuss innovative technologies involved in the design and application of optoelectronic systems and how to improve system performance or solve problems in the design of novel optoelectronic systems through a multidisciplinary approach. The following are original research papers on the optics of advanced optoelectronic devices and systems designed and studied in optical, mechanical, and control systems and airborne/space remote sensing systems.
