Abstract
Although nearly a quarter of a century has elapsed from the first theoretical prediction of quadratic optical solitons [1], a large interest has been conveyed to the topic only during the last decade [2], partially due to a mature understanding of χ(2) cascaded processes in second harmonic generation (SHG) [3]. After the first experimental demonstration of quadratic spatial solitons (QSS’s) in KTP by Torruellas et al. [4], a considerable amount of theoretical as well as experimental work has been performed, as apparent in this Volume.
