Nonlinear optics plays a key role in many applications not only as a means of frequency synthesis and control, but also as a source of twin photons and other nonclassical states of light. Advances in nonlinear materials, including engineered nonlinear interactions through the use of quasi-phase matching, have increased the flexibility and performance of(More)
