- 요약Resonance energy transfer (RET) is a common and important process in light-matter interactions in both biological and artificial systems. In RET processes, excitation energy is transferred between chromophores without them coming into contact, and is possible even if the chromophores are separated by distances on the order of dozens of nanometers. Developing the theory of RET, especially in environments with anisotropic dielectric arrangements, is a promising endeavor for understanding both natural light-harvesting processes, particularly in photosynthetic systems, and for developing design principles for efficient artificial devices and techniques. This thesis presents both the development of new theory and application of existing theory to the problem of RET optimization in complex environments. The thesis is divided into 5 chapters. Chapter 1 provides a historical introduction to RET and the theories used to describe it. This chapter details the initial Forster theory and continues through to the quantum electrodynamics (QED) description of RET that underpins the recent theoretical developments of of RET in complex systems, before setting up the work to come in the following chapters. Chapter 2 details the derivation of the RET coupling element in two spatial dimensions (2D), and uses this element to derive a similar expression for RET in a two-dimensional waveguide. The RET results in 2D and 2D waveguides point toward greater viability for long-range RET in real pseudo-2D environments. Chapter 3 serves to briefly discuss the orientation factors in the coupling element for pairwise RET in three dimensions, highlight the nontrivial extrema at the "magic angle" (cos−1√ 1 3), and discuss what this means for the deeper QED picture of the RET involving a "virtual" photon. This sets up Chapter 4, which contains research done on RET as a function of chromophore orientation using the plasmon-coupled RET theory in different environments. Three specific dielectric structures relevant to modern light-harvesting setups are subject to the analysis: plasmonic metal nanospheres, plasmonic metal planar surfaces, and metal waveguides. In the waveguide systems specifically, we find that RET can be finely tuned by orientation at specific waveguide modes. This is expanded upon in Chapter 5, in which the full RET rates and RET efficiencies (taking chromophore spontaneous emission into account) are analyzed as a function of orientation, and more possible controlling mechanisms for RET in these systems are uncovered. The thesis is concluded after a discussion of some ongoing and possible continuations in RET theory development and application.
