First integrated laser on lithium niobate chip

For all the recent advances in integrated lithium niobate photonic circuits—from frequency combs to frequency converters and modulators—one big component has remained frustratingly difficult to integrate: lasers.

Transforming computers of the future with optical interconnects

The ability to manufacture photonic interconnect components -- modulators, detectors, waveguides, and filters -- on silicon substrates has finally been realized, and these optical interconnect structures show great potential ...

Needle beam could eliminate signal loss in on-chip optics

(Phys.org)—An international, Harvard-led team of researchers have demonstrated a new type of light beam that propagates without spreading outwards, remaining very narrow and controlled along an unprecedented distance. This ...

Physicists find right (and left) solution for on-chip optics

(Phys.org) —A Harvard-led team of researchers has created a new type of nanoscale device that converts an optical signal into waves that travel along a metal surface. Significantly, the device can recognize specific kinds ...
