Realizing laterally continuous ultra-thin gold films on transparent substrates is a challenge of significant technological importance. In the present work, formation of ultra-thin gold films on fused silica is studied, demonstrating how suppression of island formation and reduction of plasmonic absorption can be achieved by treating substrates with (3-mercaptopropyl) trimethoxysilane prior to deposition. Void-free films with deposition thickness as low as 5.4 nm were realized and remained structurally stable at room temperature. Based on detailed structural analysis of the films by specular and diffuse X-ray reflectivity measurements, it is shown that optical transmission properties of continuous ultra-thin films can be accounted for 2 using the bulk dielectric function of gold. However, it is important to take into account the non-abrupt transition zone between the metal and the surrounding dielectrics, which extends through several lattice constants for the laterally continuous ultra-thin films (film thickness below 10 nm). This results in a significant reduction of optical transmission, as compared to the case of abrupt interfaces. These findings imply that the atomic-scale interface structure plays an important role when continuous ultra-thin films are considered, e.g., as semitransparent electrical contacts, since optical transmission deviates significantly from the theoretical predictions for ideal films.

“…Smaller transverse dimensions will give greater propagation loss and hence lower Q. In practice, surface roughness induced scattering leads to further increases in loss and optimizing roughness helps to manage losses to some extent 72,73 . Even though  is relatively high for plasmon mode lasers, high losses often lead to extreme pumping requirements.…”

In recent years there have been significant advances in the size and characteristics of small lasers, i.e. lasers with dimensions or modes sizes close to or smaller than the wavelength of emitted light. This work has primarily been led by innovative use of new materials and cavity designs. This article reviews some of the latest developments, particularly in metallic and plasmonic lasers, improvements in small dielectric lasers, and the emerging area of small bio-compatible/bioderived lasers. We examine the different approaches employed in small lasers to reduce size and how they lead to significant differences , particularly between metal and dielectric cavity lasers. We present potential applications for the various forms of small lasers and indicate where further developments are required.

“…Ormocomp shows the possibility of allowing for 12-nm-thick layers to be created [48], but a systematic study was not, to the best of our knowledge, made. Another polymer layer used as a seed layer is Cyclotene (also known as BCB) [48]. Leosson et al also show the possibility to reach thin layers with thicknesses of about 10 nm (Figure 2).…”

Ultra-thin films with low surface roughness that support surface plasmon-polaritons in the infra-red and visible ranges are needed in order to improve the performance of devices based on the manipulation of plasmon propagation. Increasing amount of efforts is made in order not only to improve the quality of the deposited layers but also to diminish their thickness and to find new materials that could be used in this field. In this review, we consider various thin films used in the field of plasmonics and metamaterials in the visible and IR range. We focus our presentation on technological issues of their deposition and reported characterization of film plasmonic performance.
