Investigation of plasmonic structures and spontaneous emission in semiconductor lattices

  • Joshua Spence

Student thesis: Master of Philosophy

Abstract

In this thesis, the author begins by introducing some fundamental concepts of LASERs, in order to contextualise the theoretical work conducted throughout the project. This thesis investigates the reflectance, transmission and density of modes of a variety of semiconductor lattices. This study depends on the transfer matrix method (TMM), which is commonly used in theoretical photonics modelling. Later in the thesis, the TMM is adapted for increased versatility, and is used to calculate the rate of spontaneous emission within several different semiconductor lattices. Finally, this thesis introduces the concept of a SPASER (with some discussion of various approaches), and the results of a series of plasmonic simulations are shown and discussed
