Abstract
We demónstrate concurrent frequency up-conversion and down-conversion in a quadratic nonlinear medium for the generation of correlated ultraviolet and visible rainbows with one-to-one angular and spectral correspondence, facilitating generation of continuously tunable and photon-momentum-dependent multi-wavelength UV and visible twin photons.
