Computational Nanophotonics: Basics, Challenges and Future Perspectives


Nanophotonics modelling for 21st century applications is becoming essential for the fundamental understanding of active and
passive photonic devices. This computational modeling provides elementary concepts of the relying physics behind the
operation of photonic devices. However, computational modeling is still a challenge as some of the existing modeling
techniques fail to capture the correct behavior of nano-photonic devices. In this regard, the proposed talk will introduce an
overview of the existing computational modeling tools for analyzing photonic devices and highlight their salient features and
shortcomings. It is well known that “plasmonics” plays a vital role in localizing optical fields beyond the diffraction limit, hence
crucial features in optical devices. This talk will also focus on plasmonics modeling issues and the failure of the classical
electromagnetic solvers to accurately characterize the nano-plasmonic devices. Therefore, a new accurate, and stable beam
propagation method will be introduced for analyzing plasmonics phenomena in the classical regime, relying on the finite
elements method in the wide spectrum of radiation. Moreover, in merging quantum plasmonic devices, it becomes essential
to introduce “Quantum Corrected Model (QCM)” in order to accurately model these devices, and the basics of QCM will be
also discussed.
