By carefully placing nanostructures on a flat surface, researchers at Linköping University, Sweden, have significantly improved the performance of so-called optical metasurfaces in conductive plastics. This is a major step ...
Molding the flow of light—whether confined to localized regions or propagating in free space—remains crucial for modern integrated photonics. The advancement of the multi-channel, programmable optical waveguide and coupler ...
Converting sunlight into electricity is the task of photovoltaic solar cells, but nearly half the light that reaches a flat silicon solar cell surface is lost to reflection. While traditional antireflective coatings help, ...
Polarization, along with intensity, wavelength, and phase, is a fundamental property of light. It enhances contrast and resolution in imaging compared to traditional intensity-based methods. On-chip polarization devices rely ...
Beams of light that can be guided into corkscrew-like shapes called optical vortices are used today in a range of applications. Pushing the limits of structured light, Harvard applied physicists in the John A. Paulson School ...
Researchers from ICMAB are revolutionizing how we manipulate light at the nanoscale using chiral plasmonic structures—nanomaterials designed to interact with polarized light in extraordinary ways.
Almost a decade ago, Harvard engineers unveiled the world's first visible-spectrum metasurfaces—ultra-thin, flat devices patterned with nanoscale structures that could precisely control the behavior of light. A powerful alternative ...
Capturing precise 3D details with a single camera has long been a challenge. Traditional methods often require complex dual-camera setups or specialized lighting conditions that are impractical for real-world applications. ...
Conventional curved lenses, which direct light by refraction in glass or plastic, are often bulky and heavy, offering only limited control of light waves. Metasurfaces, in contrast, are flat and consist of an array of tiny ...
Photonic circuits, which manipulate light to perform various computational tasks, have become essential tools for a range of advanced technologies—from quantum simulations to artificial intelligence. These circuits offer ...
