Devices that capture the brilliant light from millions of quantum dots, including chip-scale lasers and optical amplifiers, have made the transition from
Chip-based devices known as frequency combs, which measure the frequency of light waves with unparalleled precision, have revolutionized time keeping, the
In research, sometimes the bumpy path proves to be the best one. By creating tiny, periodic bumps in a miniature racetrack for light, researchers at the
Conventional techniques for analyzing chemical composition, such as infrared (IR) microscopy often miss critically important nanoscale details. To overcome this
Nano and atomic scale theory of the electronic, optical and mechanical properties of ultrasmall structures, such as semiconductor quantum dots and dopants in Si
Metamaterials are tailor-made photonic composites--combinations of materials designed to achieve optical properties not seen in nature. The properties stem from
The quantum optics of light interacting with semiconductor-based nanostructures is being studied to extend concepts of entanglement and coherence in atomic
