Near-infrared nano-optical elements using plasmonic nanoantennas
Near-infrared nano-optical elements using plasmonic nanoantennas
In recent years Nanophotonics, the behaviour of light at the nanometer scale has gathered Significant interest with recent advances in nanotechnology. Specifically, nanoantennas can help us access the near and mid-‐‑infrared wavelength range. The drivers are that it is a very attractive spectral region for a wide variety of technology applications, such as communications, environmental sensing, biosensing, security and astronomy.
This thesis covers the functionality of single plasmonic nanoantennas for polarisation control and nonlinear frequency conversion, characterised by quantitative single-‐‑particle extinction spectroscopy and nonlinear optical microscopy. It then moves on to look at the use of plasmonic resonators as coherent absorbers in a mechanically tunable cavity. Finally, it looks at the performance of antennas in surface enhanced Raman (SERS) and IR spectroscopy (SEIRS) using new experimental setups.

Abstract
In recent years Nanophotonics, the behaviour of light at the nanometer scale has gathered Significant interest with recent advances in nanotechnology. Specifically, nanoantennas can help us access the near and mid-‐‑infrared wavelength range. The drivers are that it is a very attractive spectral region for a wide variety of technology applications, such as communications, environmental sensing, biosensing, security and astronomy.
This thesis covers the functionality of single plasmonic nanoantennas for polarisation control and nonlinear frequency conversion, characterised by quantitative single-‐‑particle extinction spectroscopy and nonlinear optical microscopy. It then moves on to look at the use of plasmonic resonators as coherent absorbers in a mechanically tunable cavity. Finally, it looks at the performance of antennas in surface enhanced Raman (SERS) and IR spectroscopy (SEIRS) using new experimental setups.
