Integrated optical frequency combs, as a key technology in modern photonics, have attracted significant attention in recent years due to their high-dimensional modal properties in the time and frequency domains. This technology has demonstrated remarkable applications in classical optics, such as high-capacity communication, spectral analysis, and ultrafast ranging, while also enabling unprecedented capabilities for the generation and manipulation of high-dimensional quantum states in quantum op

Multiplexing technology, as a means to effectively enhance information storage and transmission capabilities, has always been of great interest. Traditional multiplexing techniques, such as angular multiplexing, positional multiplexing, orbital angular momentum multiplexing, and polarization multiplexing, hold significant importance in information storage and transmission. However, when exploring multiplexing technologies across various dimensions, the polarization dimension faces challenges due

Quantitative phase imaging (QPI) is an optical microscopy technique that quantifies the morphology and refractive index distribution of a sample by measuring the phase shift of light waves passing through it, without the need for dyes or labels. With its non-invasive and highly sensitive nature, it has found wide applications in biomedicine, materials science, and other fields. Compared to traditional intensity imaging techniques, QPI provides more structural information and is particularly suit

Nanoantennas, as miniature optical devices, have garnered significant attention due to their immense potential in fields such as super-resolution imaging, surface-enhanced Raman spectroscopy, and quantum sensing. However, because nanoantennas are much smaller than the wavelength of light—typically below the diffraction limit—precise positioning and manipulation of these nanoantennas remain urgent challenges. Traditional positioning techniques are constrained by the optical diffraction limit, mak
