Abstract
The observation of waveguided quasiphase-matched white light in proton exchanged LiNbO3 channel waveguides is reported. Second-harmonic (809.7 nm), sum-frequency (539.8 nm) and fourth-harmonic (404.9 nm) generations were obtained using a single laser source at 1619.4 nm with an improvement of 5 times over the blue light generation efficiency previously reported in KTP.Keywords
