摘要我们以前已经对各向同性有机薄膜支持的p极化长程模(LRMS)进行了分析。在这里，我们将分析扩展到单轴系统。此外，由于p极化LRMS的分析揭示了常规导波理论所不能预期的反直观的结果，我们还分析了S极化模式的情况，希望它们也能表现出令人惊讶的行为。为此，我们发现了S极化的第二个LRM，它可以由一层强吸收的各向同性薄膜支撑。给出了P偏振模和S偏振模在(400-720)nm波长范围内的光激发实验数据。
Abstract We have shown previously an analysis of the p-polarized long-range modes (LRMs) which may be supported by an isotropic thin organic film. Here we extend the analysis to a uniaxial system. In addition since the analysis of p-polarized LRMs revealed counter-intuitive results which could not be expected from conventional guided wave theory we also analysed the situation for s-polarized modes in the hope that these too would exhibit surprising behaviour. To this end we have discovered a second LRM which is s-polarized and can be supported by a strongly absorbing isotropic thin film. Experimental data for the optical excitation of both p- and s-polarized modes are presented over the wavelength range (400–720) nm.
