Fluorescence near interfaces: The role of photonic mode density

TLDR

The review surveys fluorescence near interfaces, emphasizing how photonic mode density influences fluorescence and other optical processes, and proposes future research directions. It examines recent studies on photonic mode density, covering surface and waveguide modes and non‑radiative decay mechanisms. Textured surfaces markedly modify photonic mode density and facilitate coupling of non‑radiative modes to radiation.

Abstract

Abstract A review of fluorescence near interfaces is presented. Recent work that examines the role of photonic mode density in this process is surveyed and the underlying concepts discussed. The review includes an examination of the role of surface and waveguide modes, as well as non-radiative decay. The importance of textured surfaces in providing large changes in photonic mode density and in coupling non-radiative modes to radiation is highlighted. Indications are given for future areas of research and on how photonic mode density may influence optical processes other than fluorescence.
