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 .

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 ...

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 .

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

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.
