Photothermal Heating in Plasmonic Nanostructures

Scroll Prev Top Next More

In this example, we investigate the effect of photothermal heating in plasmonic nanostructures based on the published work in the referenced article [1].  Using Lumerical's FDTD for optical simulation and Heat Transport Solver for thermal simulation, we look at two types of thermoplasmonic antennae; dipole and diabolo.  In the first part of this example we consider arrays of both these antennae under varying optical intensity and compare their performance.  In the second part of this example we look at a single diabolo antenna and demonstrate how its performance can be greatly enhanced by employing a plasmonic lens.
