Single and multi-mode directional lasing from arrays of dielectric nanoresonators
Shaimaa I. Azzam, Krishnakali Chaudhuri, Alexei Lagutchev +5
The strong electric and magnetic resonances in dielectric subwavelength structures have enabled unique opportunities for efficient manipulation of light-matter interactions. Beside…
All-optical Nonlinear Activation Function for Photonic Neural Networks
Mario Miscuglio, Armin Mehrabian, Zibo Hu +5
With the recent successes of neural networks (NN) to perform machine-learning tasks, photonic-based NN designs may enable high throughput and low power neuromorphic compute paradig…
Full-wave analysis of reverse saturable absorption in time-domain
Shaimaa I. Azzam, Alexander V. Kildishev
An advanced full-wave time-domain numerical model for reverse saturable absorption (RSA) is presented and verified against established methods. Rate equations, describing atomic re…
Formation of Bound States in the Continuum in Hybrid Plasmonic-Photonic Systems
Shaimaa I. Azzam, Vladimir M. Shalaev, Alexandra Boltasseva +1
A bound state in the continuum (BIC) is a localized state of an open structure with access to radiation channels, yet it remains highly confined with, in theory, infinite lifetime…
