The development of InGaAs/InP single-photon avalanche photodiodes (SPADs) necessitates the utilization of a two-element diffusion technique to achieve accurate manipulation of the multiplication width and the distribution of its e

Metasurfaces in the long wave infrared (LWIR) spectrum hold great potential for applications in thermal imaging, atmospheric remote sensing, and target identification, among others. In this study, we designed and experimentally de

Variable optical attenuator (VOA) arrays can be widely applied in optical communication and optoelectronic systems, but few VOA arrays are reported. Here a liquid-stop based microfluidic VOA array is proposed. It uses a spiral orb

Photoreflectance (PR) has been widely used for the characterization of various semiconductors as well as their surface and interface properties due to its non-destructive and high sensitivity virtues. From the viewpoint of the emp

As the cell size of uncooled infrared (IR) detectors progressively shrinks, it becomes increasingly important to increase detector absorption. here, an IMIAM (Insulator-Metal-Insulator-Air-Metal) cavity type metasurface uncooled I

Through sufficient investigation and summary, the development trend and representative work of Metaverse and related technologies in the aerospace field since the 1960s have been sorted out, and it is pointed out that multi-satell

In this paper, a dual-band graphene-based frequency selective surface (GFSS) is investigated and the operating mechanism of this GFSS is analyzed. By adjusting the bias voltage to control the graphene chemical potential between 0

To meet the high-speed and high-capacity demands of communication, a 300GHz electronic wireless transmission system for terahertz frequencies is proposed, which incorporates Probability Shaping (PS), Discrete Multi-tone Modulation

Terahertz (THz) technology is undergoing a rapid development in biomedical applications. Researchers have made a series of important achievements in the study of biological samples on various levels such as biomolecules, cells, ti
