Exploring the equivalence of causality-based and quantum mechanics-based sum rules for harmonic generation in nonlinear optical materials
Theodoros T. Koutserimpas, Hao Li, Owen D. Miller +1
The Kramers-Kronig relations and various oscillator strength sum rules represent strong constraints on the physical response of materials. In this work, taking inspiration from the…

Approaching upper bounds to resonant nonlinear optical susceptibilities with inverse-designed quantum wells
Hao Li, Theodoros T. Koutserimpas, Francesco Monticone +1
We develop a unified framework for identifying bounds to maximum resonant nonlinear optical susceptibilities, and for "inverse designing" quantum-well structures that can approach…
