Devices that process light signals the way traditional circuits process electronic signals can now work in a technologically important wavelength range. Nanoscale structures called metatronic circuits ...
Scientists have created a programmable optical chip that can slow light on demand, giving engineers far greater control over how optical signals propagate through a circuit. The technology could ...
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 ...
