Abstract

We describe the use of nonlinear feedback to tune the cubic nonlinearity of a silicon nanowire resonator. We show that nonlinear feedback can be used to cancel out the native nonlinearity or even change its sign. Here, we demonstrate the usefulness of this technique by using nonlinear feedback to extend the dynamic range of a silicon nanowire parametric amplifier.
