Abstract

Recent studies have shown that the incorporation of scandium (Sc) can transform AlN to be ferroelectric. The resulting ferroelectric ScAlN exhibits significantly enhanced electrical, piezoelectric, as well as linear and nonlinear optical properties. These unique characteristics, together with its ultrawide bandgap, ferroelectric functionality, and seamless integration with III-nitride technology, have made ScAlN a very promising platform for future integrated quantum photonics. Here, we report on the epitaxy of single crystalline ferroelectric ScAlN and the demonstration of ScAlN waveguides, ring resonators, and modulators, which offer, for the first time, the ability to truly unlock the potential of this material system.
