In the early digital era, logic gates were made exclusively of transistors and discrete components. The obvious occupation of a large space and increased heat dissipation pushed technology to ...

Optical waveguides are structures that guide and confine light within a small cross-sectional area. In nanophotonic circuits, waveguides are typically fabricated using high-refractive-index materials ...

Why it matters: For decades, scientists have dreamed of building computer chips that use light instead of electricity to process information. While our current silicon chips are incredibly fast, ...
