Lumerical's products help research professionals better understand the unique optical properties of nanoparticles and their strong dependence on size and material composition
Overview
Nanoparticles are an area of intense scientific research owing to the interesting, size-dependent physical properties that such nanoparticles exhibit. In the field of photonics, nanoparticles of appropriate size are capable of strongly scattering or absorbing incident electromagnetic radiation when, for example, surface plasmon resonances are excited in metallic nanoparticles. Nanoparticles formed from semiconducting materials are able to form quantum dots, which can exhibit interesting emission properties.
Nanoparticles are of interest for applications spanning the biotechnology, sensing, and photovoltaic industries.

 "Our experience using parallel FDTD Solutions on a dual quad core Xeon Processor workstation has been fantastic! It greatly helped us in decreasing processing time for our plasmon-enhanced fluorescence calculations and hence greatly increased our computational throughput. We are extremely satisfied with the parallel version of FDTD Solutions and would recommend it to the scientific community at large.
