“…These propagation lengths are the result of the reduced or increased absorption due to the field distribution in the conducting layer [24]. In 1978 Kovacs demonstrated that high losses in thin slabs of metals is not an impediment for the excitation of long-surface surface modes [25]. This work was extended by Yang and co-workers to non-metallic materials with very large absorption at infrared frequencies [26].…”

Abstract:We propose a novel method to guide THz radiation with low losses along thin layers of water. This approach is based on the coupling of evanescent surface fields at the opposite sides of the thin water layer surrounded by a dielectric material, which leads to a maximum field amplitude at the interfaces and a reduction of the energy density inside the water film. In spite of the strong absorption of water in this frequency range, calculations show that the field distribution can lead to propagation lengths of several centimeters. By means of attenuated total reflection measurements we demonstrate the coupling of incident THz radiation to the long-range surface guided modes across a layer of water with a thickness of 24 μm. This first demonstration paves the way for THz sensing in aqueous environments.

“…A classical waveguide structure is a metal film placed between two dielectric materials with the same permitivity. Two different modes can be excited in such symmetric structure [12] [13]. In another, more widespread asymmetric limiting case, a film of finite thickness is limited on both sides by media with different refractive indices.…”

The spectral characteristics of surface plasmon resonance (SPR) in nanosized gold films were studied with method of internal reflection in the Kretschmann geometry. Using modulation polarimetry technique, we measured the spectral and angular characteristics of the parameter 2 2 fering in frequency and amplitude) is shown. The resonance parameters are determined and used for construction of dispersion curves ( ) k ω . Their interpretation is given based on the theoretical model for waveguide modes on both metal film surfaces that were proposed earlier.

“…These modes arise from the coupling of the evanescently decaying electromagnetic field, as a result of the strong absorption, at the opposite sides of the thin layer. In spite of the similarities between long-range surface plasmon polaritons and long-range guided modes in absorbing thin films there are only a hand-full of articles about the last [12][13][14][15] and, to the best of our knowledge, none about optical sensing.…”

We demonstrate the excitation of guided modes in thin layers of strongly absorbing chalcogenide glasses. These modes are similar to surface plasmon polaritons in terms of resonance width and shift with changes in the permittivity of the surrounding medium. We exploit these characteristics to demonstrate a high sensitivity chalcogenide glass refractive index sensor that outperforms gold surface plasmon resonance sensors at short wavelengths in the visible. This demonstration opens a new range of possibilities for sensing using different materials.
