Sensory hair cells in the inner ear combine into hair bundles to convert sound waves into electrical signals. Both single-cell and organ-wide directionality are critical for hearing, but these two ...

Researchers have cracked a fundamental optical challenge: how to control both angle and wavelength of light independently—a problem that’s limited imaging and display technologies for years. By ...

Wavelength and propagation direction (angle) are two fundamental properties of light. The ability to selectively control both a specific wavelength and a specific angle forms the physical foundation ...

Researchers use circularly polarized light to control the direction of exciton polaritons in 2D semiconductors, enabling new tools for nanoscale photonics. (Nanowerk Spotlight) Directing light along ...
