a) Illustration of the omnidirectional wavelength-tunable color device featuring a mechanochromic chiral liquid crystal elastomer (CLCE) and an electrically deformable dielectric elastomer actuator ...

To overcome the lack of wavelength-selective extraction in existing on-chip metasurfaces, Chinese scientists developed a novel approach by leveraging a nonlocal on-chip design based on symmetry-broken ...

For example, the coatings on tinted eyeglasses reflect, or "block out," harmful blue light and ultraviolet rays. But until now, no optical coating had ever been developed that could simultaneously ...

Currently, Kyocera's technology enables aerial images whose focal positions vary by color. In the future, increasing the degree of wavelength control could allow full-color, high-resolution aerial ...
