Second Harmonic Generation and χχ⁽²⁾ Cascading in Periodically Poled MgO:LiNbO₃ Photonic Wires 2024 (English)In: The 25th European Conference on Integrated Optics - Proceedings of ECIO 2024, Springer Nature , 2024, p. 145-148Conference paper, Published paper (Refereed)

Abstract [en]

We study second harmonic generation in LiNbO3 nanowaveguides, operated with sub-pJ pulses at 1424 nm in the picosecond regime generating 0.5 μW at 712 nm. Spectra recorded at both wavelengths provide evidence for enhanced χ(2) cascading effects.
