Abstract:

Nonlinear on-chip optical devices using AlScN are described herein. In one aspect, an optical component having nonlinear characteristics can include a first substrate defining a refractive index; and a nonlinear layer, the nonlinear layer disposed on the first substrate, the nonlinear layer comprising an amount of scandium (Sc), and the nonlinear layer defining a refractive index that is higher than the refractive index of the first substrate.
