Overview: The spatial resolution of traditional optical microscopy is limited by the diffraction limit λ/(2NA) (λ is the wavelength, NA is the numerical aperture of the objective lens of system), and the lateral resolution is abou

Overview: In recent years, vortex beams have become the focus of research, and their orbital angular momentum makes them have many important applications, like optical communication, particle manipulation, and optical measurement.

Overview: Featured by the capability of multi degree-of-freedom light-field manipulations while reserving high spatial resolution, multifocal laser arrays have been widely applied in femtosecond laser micro/nanofabrication, optica

Overview: Polarization holography has important application prospects in the field of data storage and polarized light imaging due to its ability to record amplitude, phase, and polarization information. In addition, it also has t

Overview: Optical coherence, as a fundamental resource in all areas of optical physics, plays a vital role in understanding interference, propagation, scattering, imaging, light-matter interactions, and other fundamental character

Overview: Surface plasmon resonance (SPR) sensing technology has attracted widespread attention due to its advantages of high sensitivity, label-free, and real-time dynamic monitoring. Traditional SPR sensing platform needs the us

Overview: Optical super-resolution lenses have shown great potential in super-resolution microscopic systems and nano-fabrication systems. With the decrease of the focusing spot of the super-resolution lens, it is inevitable that
