An optomechanical single-photon frequency shifter is demonstrated in integrated AlN waveguides. A frequency shift up to 150 GHz is achieved at telecom wavelength. The device shows near-unity ...

Researchers at the Leibniz Institute of Photonic Technology (Leibniz IPHT) in Jena, Germany, together with international ...

Photon frequency doubler is controlled by light. 21 Jan 2020 Doubling up: ... electrons in the triangles gain energy and some of these “hot electrons” move onto the titanium dioxide via the triangle .

Q.ANT's new chip uses photon power in a bid to solve AI's big energy issue. It's also 50 times faster than silicon-based equivalents, the company says.

In this case, q photons of fundamental frequency ω 0 are up-converted to a frequency chosen to satisfy momentum conservation, . The related energy mismatch (resulting from dispersion) is .
