Polaritonic materials fabricated and tested with ultrashort-pulse lasers
David W. Ward, Eric R. Statz, Thomas Feurer +1
Using femtosecond laser machining, we have fabricated photonic bandgap materials that influence propagation of phonon-polaritons in ferroelectric crystals. Broadband polaritons wer…
Finite Difference Time Domain (FDTD) Simulations of Electromagnetic Wave Propagation Using a Spreadsheet
David W. Ward, Keith A. Nelson
We describe a simple and intuitive implementation of the method of finite difference time domain simulations for propagating electromagnetic waves using the simplest possible tools…
Simulation of Phonon-Polariton Generation and Propagation in Ferroelectric LiNbO3 Crystals
David W. Ward, Eric Statz, Nikolay Stoyanov +1
We simulate propagation of phonon-polaritons (admixtures of polar lattice vibrations and electromagnetic waves) in ferroelectric LiNbO3 with a model that consists of a spatially pe…
Phonon-Polariton Propagation, Guidance, and Control in Bulk and Patterned Thin Film Ferroelectric Crystals
David W. Ward, Eric Statz, Jaime D. Beers +5
Using time resolved ultrafast spectroscopy, we have demonstrated that the far infrared (FIR) excitations in ferroelectric crystals may be modified through an arsenal of control tec…
The Role of Multiferroics in the Negative Index of Refraction
David W. Ward, Eric Statz, Kevin J. Webb +1
We explore the possibility of realizing intrinsic far infrared negative index materials (NIM) in multiferroic crystals (crystals simultaneously possessing a ferroelectric and ferro…
