实验证明，强吸收硫化物薄膜可以支持长程表面极化子。此外，改变这种材料的相的可能性使我们能够研究薄膜的介电常数对表面模的影响。我们证明了这些模式对薄膜的介电常数相对不敏感。将支持长程表面极化子的材料范围扩大到强吸收层，为被认为仅限于弱吸收介质的应用开辟了新的可能性。
We demonstrate experimentally that strongly absorbing chalcogenide thin films can support long range surface polaritons. Moreover, the possibility to change the phase of this material allows us to investigate the influence of the permittivity of the thin film on the surface modes. We demonstrate the relative insensitivity of these modes to the permittivity of the thin film. Extending the range of materials that support long range surface polaritons to strongly absorbing layers opens new possibilities for applications that were thought to be limited to weakly absorbing media.
