A chip-scale broadband light source in silicon carbide

Optical frequency combs have changed science and technology as we know it. Responsible for measuring things like infrared and ultraviolet light, greenhouse gases, atomic clocks, and disease, optical frequency combs act as ...

Fiber-optic cables can produce high-resolution underground maps

How much the ground moves during an earthquake strongly depends on properties of rock and soil just beneath Earth's surface. Modeling studies suggest that ground shaking is amplified in sedimentary basins, on which populated ...

When light loses symmetry, it can hold particles

Optical tweezers use light to immobilize microscopic particles as small as a single atom in 3D space. The basic principle behind optical tweezers is the momentum transfer between light and the object being held. Analogous ...
