Metalenses based on optical superoscillation principles are widely applied in super-resolution imaging and can be achieved using inverse design methods. However, traditional approaches predominantly rely on heuristic algorithms, which perform random searches within the solution space. This results in low design efficiency …

Terahertz generation and detection is the key means to explore terahertz spectrum, one of which is the application of photoconductive antenna. In this study, a low-temperature gallium arsenide (LT-GaAs) epitaxial wafer antenna and an LT-GaAs thin-film antenna were fabricated. The LT-GaAs epitaxial …

A new method of generating and detecting terahertz waves is proposed. Low-temperature-grown gallium arsenide (LT-GaAs) thin films are prepared by etching a sacrificial layer (AlAs) in a four-layer epitaxial structure constituted with LT-GaAs, AlAs, GaAs, and semi-insulating gallium arsenide (SI-GaAs). The thin …

We report an active broadband terahertz (THz) modulator based on a Fe3O4nanoparticle/silicon (Si) structure, where the interface effects were measured in a homemade THz time-domain spectroscopy system. An approximately 100-nm Fe3O4nanoparticle thin film on the high-resistance Si substrate was easily attained by …
