This book is built on the recent advancements in understanding thermoplasmonics and highlights the exciting new directions that are shaping this field. Thermoplasmonics using light to heat nanostructures is a promising and rapidly expanding subfield of plasmonics. When the light frequency matches the oscillation frequency of free electrons on the nanostructures, it induces a collective oscillation known as plasmon resonance. This effect allows fantastic control over the optical field at sub-wavelength scales, enhancing the light-matter interaction to surmount the diffraction limits. The plasmon resonance is responsible for fascinating and tunable properties, such as local field enhancement, generation of hot electrons as well as the localized/collective heating. These energetic carriers and heat can be harvested to drive a wide range of physical and chemical processes, making them promising for different fields of science. In this book, we discuss the recent advances in understanding of thermoplasmonics and highlight some of the exciting new directions, covering aspects of its principles, materials, and characterization, along with the diverse applications. The basic fundamentals are first introduced from plasmonic theory and thermodynamics to the thermal-induced processes. Then, much effort is placed on examination of thermoplasmonic materials and the common synthesis methods. The strategies for proper material selection and rational structural design are summarized toward more efficient energy conversion. The synthesizing methods for novel nanostructures are presented with a goal to achieve optimal thermoplasmonic properties. Afterward, the characterization technologies for thermoplasmonics are also addressed, which involves analytic and computational approaches as well as nanoscale thermometry. For each application, the unique role of thermoplasmonics and their associated benefits are elaborated. Research trends and insights into the use of thermoplasmonics to improve performance are analyzed as well. Finally, the current challenges and future perspectives in this field are pointed out in this book.

In the last decades, optics has become central in many applications in modern society. Nano-optics, which studies the behavior of light at the nanoscale, holds promise to do the same. However, when using traditional optical elements such as mirrors and lenses to control light propagation, there is a fundamental limit on the localization of the field which could a priori impinge on the ability to use optics at the nanometer scale. One way to improve the confinement of electromagnetic waves is to couple light with materials that have high dielectric permittivity. In this context, a particular interest has been devoted to metallic nanostructures made of gold, silver or aluminum. In this case the interaction can lead to a coherent collective electron oscillation and is known as a Surface Plasmon (SP). Such enhanced interaction results in both strong absorption and scattering of light. An inherent effect in such systems is the unavoidable damping of the SP. This causes internal Joule dissipation, which results in heat generation. Although this phenomenon is considered to be a drawback in many plasmonic applications, recent studies have shown the promise of nanoscale heat generation for both physical and biological application. This strategy is at the basis of a rapidly growing field called Thermo-Plasmonics. Controlling, exploiting and monitoring plasmonic heating is the topic of my PhD. In the first chapter of the thesis, the Joule effect induced in plasmonic nanoparticles is described. Thereafter, this concept is used to develop both physical and biological applications which rely on the ability to control nanoscale temperature in order to perturb the surrounding environment. A physical application consisting of a fast tunable Photothermal Lens based on plasmonic heating is described in the third chapter. To this end, we develop a model to predict the lens behavior. Next, experimental characterization of a fabricated thermal lens is performed. Finally, we show that such a system could be used for fast and accurate focal plane tunability as well as for adaptive optics applications. In the fourth chapter I describe another thermo-plasmonic based application which relies on the use of nanoscale heat generation to modify and even control the fluid flow in a micro-fluidic system. To do so, we numerically calculate the fluid convection that is induced by plasmonic heating at the micro and nanoscale. Next, an experimental implementation of a microfluidic pump based on plasmonic heating is presented. The applications mentioned above rely on the efficient opto-thermal conversion in gold nano particles to generate local heat sources. One advantage of gold is that it is nontoxic, allowing the application of thermo-plasmonics to bio systems. This is a pertinent line of investigation, because temperature is a basic parameter which influences many cellular biological processes. Nanotechnology is not only providing new ways to generate point like heat sources but also to accurately monitor the resulting temperature maps. Within this context, we developed a tool that permits the measurement of temperature at the nanoscale in biological systems. This is done by monitoring the fluorescence polarization anisotropy (FPA) of a fluorescent molecule. Specifically, in the fifth chapter I present the use of Green Fluorescent Protein (GFP) as a thermal nanoprobe suited for in vitro cellular temperature mapping. This is performed by monitoring the FPA of the GFP. We apply this method to measure the temperature generated by photothermal heating of gold nanorods inside and outside cells. Consequently, we extend this technique and perform the first in vivo intracellular thermal imaging. In the sixth chapter we demonstrate this method with GFP expressing neurons of a worm. In both cases we show that the method enables diffraction limited spatial resolution, good temperature accuracy and fast readout together with high bio-compatibility.

Silicon photonics offers a cost effective solution to achieve ultrafast data processing speeds. But due to its indirect bandgap structure, making lasers from silicon is extremely difficult. Thus research has focused on nonlinear Raman processes in silicon as a method to achieve optical gain. Silicon nanowires provide an interesting platform for enhancing these nonlinearities because of their small size, geometry and relevant length scales. In the current work Raman measurements done on silicon nanowires reveal that up to twelvefold enhancement in Stokes scattering intensity and fourfold enhancement in anti Stokes scattering intensity can be attained depending on cavity structure and size, and excitation wavelength. In some cavities Stokes intensity depends on the sixth power of pump intensity, indicating extreme nonlinearity. Numerical calculations, done to understand the mechanism of these results indicate that silicon nanowires confine light to highly intense electric field modes inside the cavity which lead to stimulated Stokes and anti Stokes Raman scattering. Cavity modes can also be tuned to enhance the relative emission of either one of anti Stokes or Stokes photons which could enhance cavity cooling. These results would enable the development of smallest monolithically integratable silicon laser with extremely low lasing threshold and could lead to the development of next generation of high speed and energy efficient processors. The intense electric field inside the nanowire could also be used to enhance the degree of plasmon excitation in metallic nanoparticles. Silicon nanowires coated with a 10 nm thick gold film lead to strong plasmon excitation in gold and high cavity absorption which enable the cavity to heat up to temperatures of 1000K at relatively low pump powers. The cavities also give the ability to measure temperature attained during plasmon excitation and control the plasmon resonance wavelength. Because of the strong heating and plasmonic effects, these cavities show enhanced evolution rates of hydrogen, a crucial industrial building block and a promising fuel, in photoreforming reactions of alcohols.
