Nanoscale Plasmonic Emitters for Ultra-high Intensity Thermal Pulse Generation
Abstract
Nanophotonics and plasmonics offer a promising low-cost solution for simulating thermal pulses of nuclear outputs at small scales due to the light concentration and field strength enhancement. Although plasmonic or nanophotonic structures, such as plasmonic antennas, resonant metamaterials, and photonic crystal cavities, have been identified as a common paradigm for realizing spectrally tunable and high-intensity thermal emission, the limit of using plasmonic or nanophotonic structures for generating highly intensive thermal pulses still remains unclear. In this project, we will develop a new theory to study the limit of thermal output power from an arbitrary plasmonic emitter, and to design novel plasmonic thermal emitters to achieve ultra-high intensity. We will also fabricate the plasmonic thermal emitters using refractory metals and graphene, and demonstrate their high intensity in both near- and far-fields.
