We study the effect of geometry on the nonlinear response of a network of quantum wires that form loops. Exploiting the fact that a loop’s transition moment matrix and energies are exactly solvable for each wire segment, they can be pieced together to determine a loop’s properties. A Monte Carlo method is used to sample the configuration space of all possible geometries to determine the shape that optimizes the intrinsic hyperpolarizability. We suggest that a combination of wire geometry and confinement effects can lead to artificial systems with ultra-large nonlinear response, which can be potentially made using known nanofabrication techniques.
