Nonlinear optical interactions can be substantially enhanced by the wavelength-scale confinement in integrated photonics, providing transformative capabilities for controlling, enhancing and manipulating material nonlinearities in miniaturized platforms. In this Review, we outline the design principles that harness the potential of nonlinear optical materials on integrated platforms and their utility in applications including broadband frequency conversion, frequency-comb generation, quantum light sources and nonlinear optical quantum logic gates.
