Spectral super-resolution (sSR) is a very important technique to obtain hyperspectral images
from only RGB images, which can effectively overcome the high acquisition cost and low …

Recent rapid progress in metasurfaces is underpinned by the physics of local and nonlocal
resonances and the modes coupling among them, leading to tremendous applications such …

Light scattered or radiated from a material carries valuable information on the said material.
Such information can be uncovered by measuring the light field at different angles and …

While conventional photodetectors can only measure light intensity, the vectorial light field
contains much richer information, including polarization and spectrum, that are essential for …

Hyperspectral imaging is vital for material identification but traditional systems are bulky,
hindering the development of compact systems. While previous metasurfaces address …

Metasurfaces have an exceptional capacity to manipulate the phase, amplitude,
polarization, or spectrum of light. However, unit cells, or meta‐atoms, of metasurfaces are …

Dispersion decomposes compound light into its monochromatic components, which is
detrimental to broadband imaging but advantageous for spectroscopic applications …

Sorting orbital angular momentum (OAM) and spin angular momentum (SAM) of photons is
crucial for optical communications, optical storage, and quantum information processing …

Miniaturization of optical spectrometers is important to enable spectroscopic analysis to play
a role in in situ, or even in vitro and in vivo characterization systems. However, scaled-down …

Spiral phase contrast imaging and bright-field imaging are two widely used modes in
microscopy, providing distinct morphological information about objects. However …
