Abstract: This thesis comprises two research projects focused on investigating surface plasmon (SP) propagation on metal-dielectric interfaces. The characterization of a newly fabricated device, designed for further research, is also presented. This thesis first showcases a new form of SP lasing, which utilizes two metal hole arrays as cavity mirrors. Analysis of the lasing mode provides a direct view of SP propagation and allows for determining the SP group velocity on any metal-dielectric interface. Second, high-quality measurements of the dispersion characteristics of SP-mediated emission from an actively pumped elliptical-hole array are presented. These measurements resulted in the observation of an intriguing SP dispersion relation ω(k) and provide an insight into the effect of symmetry-breaking of SP scattering in metal hole arrays. Looking into the future, this thesis also describes the production process as well as subsequent characterization of a newly fabricated device. The device is found to perform worse than expected, leading to several interesting insights into the production process.
