A method to accurately center quantum dots within photonic chips

Devices that capture the brilliant light from millions of quantum dots, including chip-scale lasers and optical amplifiers, have made the transition from laboratory experiments to commercial products. But newer types of quantum-dot ...

Could iPhones replace microscopes in early STEM education?

Widespread ownership of modern smartphones could make for more accessible—and equitable—microscopy in many elementary and middle school classrooms. According to University of Georgia research, iPhone cameras can serve ...

Scientists unveil a DIY structured-illumination microscope

For hundreds of years, the optical microscope was the only tool available to scientists wanting to study the movement of cells, bacteria and yeast. But the diffraction of light made it impossible to observe objects at resolutions ...
