DOI: 10.1021/acsphotonics.4c01892
Abstract: We develop a unified framework for identifying bounds to maximum resonant nonlinear optical susceptibilities, and for"inverse designing"quantum-well structures that can approach such bounds. In special cases (e.g. second-harmonic generation) we observe that known bounds, a… read more here.

DOI: 10.1364/oe.567729
Abstract: Scalar-based isotropic inverse design algorithms have been widely adopted. However, anisotropic materials pose challenges for scalar-based inverse design methods due to their direction-dependent refractive index distributions, which particularly limit the application of X-cut lithium niobate… read more here.
