A Finite-Difference Time-Domain approach for dispersive magnetic media
Jasmin Graf, Joshua Baxter, Sanchar Sharma +2
We extend the Finite-Difference Time-Domain method to treat dispersive magnetic media by incorporating magneto-optical effects through a frequency-dependent permittivity tensor. Fo…
Inverse design of optical pulse shapes for time-varying photonics
Joshua Baxter, Lora Ramunno
There has been an explosion of interest in time-varying photonics due to the recent discovery and design of materials and metamaterials with strong, time-varying, nonlinear optical…
Understanding the nonlinear optical response of epsilon near zero materials in the time-domain
Joshua Baxter, Adriana Pérez-Casanova, Luis Cortes-Herrera +3
The promise of active nanophotonics technology relies on the confinement and control of light at the nanoscale. Confinement via plasmonics, dielectric resonators, and waveguides ca…
Hyperpolarizability of plasmonic meta-atoms in metasurfaces
M. Saad Bin-Alam, Joshua Baxter, Kashif M. Awan +7
Plasmonic metasurfaces are promising as enablers of nanoscale nonlinear optics and flat nonlinear optical components. Nonlinear optical responses of such metasurfaces are determine…
Parallel FDTD modelling of nonlocality in plasmonics
Joshua Baxter, Antonino Calà Lesina, Lora Ramunno
As nanofabrication techniques become more precise, with ever smaller feature sizes, the ability to model nonlocal effects in plasmonics becomes increasingly important. While nonloc…
Plasmonic colours predicted by deep learning
Joshua Baxter, Antonino Calà Lesina, Jean-Michel Guay +3
Picosecond laser pulses have been used as a surface colouring technique for noble metals, where the colours result from plasmonic resonances in the metallic nanoparticles created a…
