Programmable on-chip nonlinear photonics.

ABSTRACT: Nonlinear optics¹ plays a central role in many photonic technologies, both classical^2-5 and quantum^6-8. However, the function of a nonlinear-optical device is typically determined during design and fixed during fabrication⁹, restricting the use of nonlinear optics to scenarios in which this inflexibility is tolerable. Here we present a photonic device with highly programmable nonlinear functionality: an optical slab waveguide with an arbitrarily reconfigurable two-dimensional distribution of χ⁽²⁾ nonlinearity. The nonlinearity is realized using electric-field-induced χ⁽²⁾ (refs. ^10-16), and the programmability is engineered by massively parallel control of the electric-field distribution within the device using a
