PARAMETRIC INTERACTIONS IN WAVEGUIDES REALIZED ON PERIODICALLY POLED CRYSTALS

摘要

In nonlinear optics, a waveguide configuration presents the advantage of a higher power confinement and a larger number of phase matching schemes. These advantages are counterbalanced by a certain number of extra requirements and a greater technological complexity. In this paper, these issues will be addressed by a quick review of different configurations which have been experimentally tested, and, as several studies are still underway, the state of the art will be presented.
