Exact fundamental limits of the first and second hyperpolarizabilities
Rick Lytel, Sean Mossman, Ethan L. Crowell +1
This letter calculates the exact fundamental limits of the first (β) and second (γ) hyperpolarizabilities using Monte-Carlo sampling of energy spectra and transition moments constr…
General solution to nonlinear optical quantum graphs using Dalgarno-Lewis summation techniques
Rick Lytel, Sean M. Mossman, Mark G. Kuzyk
We develop an algorithm to apply the Dalgarno-Lewis (DL) perturbation theory to quantum graphs with multiple, connected edges. We use it to calculate the nonlinear optical hyperpol…
Fundamental limits on the electro-optic device figure of merit
Sean Mossman, Rick Lytel, Mark G. Kuzyk
Device figures of merit are commonly employed to assess bulk material properties for a particular device class, yet these properties ultimately originate in the linear and nonlinea…
Physics of the fundamental limits of nonlinear optics: A theoretical perspective
Rick Lytel
The theory of the fundamental limits (TFL) of nonlinear optics is a powerful tool for experimentalists seeking to create molecules and materials with large responses, and for theor…
Dalgarno-Lewis perturbation theory for nonlinear optics
Sean Mossman, Rick Lytel, Mark G. Kuzyk
We apply the quadrature-based perturbation method of Dalgarno and Lewis to the evaluation of the nonlinear optical response of quantum systems. This general operator method for per…
Phase disruption as a new design paradigm for optimizing the nonlinear-optical response
Rick Lytel, Sean M. Mossman, Mark G. Kuzyk
The intrinsic optical nonlinearities of quasi-one dimensional structures, including conjugated chain polymers and nanowires, are shown to be dramatically enhanced by the judicious…
Optimization of eigenstates and spectra for quasi-linear nonlinear optical systems
Rick Lytel, Sean M. Mossman, Mark G. Kuzyk
Quasi-one-dimensional quantum structures with spectra scaling faster than the square of the eigenmode number (superscaling) can generate intrinsic, off-resonant optical nonlinearit…
Optimum topology of quasi-one dimensional nonlinear optical quantum systems
Rick Lytel, Shoresh Shafei, Mark G. Kuzyk
We determine the optimum topology of quasi-one dimensional nonlinear optical structures using generalized quantum graph models. Quantum graphs are relational graphs endowed with a…
Dressed quantum graphs with optical nonlinearities approaching the fundamental limit
Rick Lytel, Mark G. Kuzyk
We dress bare quantum graphs with finite delta function potentials and calculate optical nonlinearities that are found to match the fundamental limits set by potential optimization…
Scaling and universality in nonlinear optical quantum graphs containing star motifs
Rick Lytel, Shoresh Shafei, Mark G. Kuzyk
Quantum graphs have recently emerged as models of nonlinear optical, quantum confined systems with exquisite topological sensitivity and the potential for predicting structures wit…
Geometry-Controlled Nonlinear Optical Response of Quantum Graphs
Shoresh Shafei, Rick Lytel, Mark G. Kuzyk
We study for the first time the effect of the geometry of quantum wire networks on their nonlinear optical properties and show that for some geometries, the first hyperpolarizabili…
