Abstract
Plasmonic nanowire lasers are nanoscopic sources of light operating at deep subwavelength scales with ultrafast dynamics.[1-6] Such lasers enable the investigation of enhanced light-matter interactions and can have large impact on applications in the fields of non-linear optics, sensing, and optical communications.[7-12] However, metal-based lasers suffer from high losses, caused by the inherent electron scattering in metals, which leads to an increased lasing threshold and limits their use in applications. To minimise losses and thus improve their performance, it has been suggested to use metal films of high quality which ideally have an ultra-flat surface with a high crystalline perfection.[1, 13-16] However, investigating the effects of Ag film quality on the performance of hybrid-plasmonic zinc oxide (ZnO) nanowire lasers this work finds that such a laser geometry is dominated by losses in the gain material.
