One of the characteristic features of the metil claded dielectric waveguides different from the simple dielectric waveguides is that the former can excite guided waves with effective mode index N<1, which has the propagation constant less than the wave-number of the light in vacuum: ?/c. Authors measured directly the dispersion properties for N>1 and N<1 modes in the metal claded dielectric waveguides by the frequency scanning ATR method. The experimental results are in agreement with the theoretical calculations....

One of the characteristic features of the metil claded dielectric waveguides different from the simple dielectric waveguides is that the former can excite guided waves with effective mode index N<1, which has the propagation constant less than the wave-number of the light in vacuum: ?/c. Authors measured directly the dispersion properties for N>1 and N<1 modes in the metal claded dielectric waveguides by the frequency scanning ATR method. The experimental results are in agreement with the theoretical calculations. It is found that the coupling efficiency through the prism coupler to the metal claded dielectric waveguide is depending on the thickness of the metal coupling layer.The coupling efficiency reaches to the maximum when the thickness of the coupling layer is about 130A. The thickness of the coupling layer will influence the mode index of the waveguide owing to the slight changes of the dielectric constant of the coupling layer versus its thickness during their evaporation deposition in a vacuum coating system.

A surface polariton is the electromagnetic wave localized at the surface of the medium coupled to an elementary excitation of a condensed medium. The detailed study of surface polariton gives information about optical properties of semiconductors. In this paper, the effect of lattice vibration on the dispersive properties of the coupled system of surface electromagnetic wave and exciton is studied. The dispersion relations of the coupled system are obtained. These relations are as followss:(heavier exciton)kx(ω)=[H(F+1)2/(G2-(F + l)2)]1/2 (lighter exciton) It is found that in the case of heavier exciton, surface optical phonons have a great influence upon the coupled system of surface electromagnetic wave and exciton. As the wavevector ck/ω0→0, the frequency of the system approaches to a definite value, 0.599. As the wavevector is very large, the dependence of the wavevector on the frequency is linear. For the lighter exciton or exciton with smaller effective mass, the effect of surface optical phonons on the coupled system is small except the region near the excitonicresonance frequency. When the frequency is in the region of ,the abnormal dispersion appears which is due to resonance interaction between exciton and the surface electromagnetic wave and which is the fine-structure of resonance line of exciton. This character should deserve extra attension which is not referred to before. In conclusion, the effect of lattice vibration on the dispersive property of the coupled system of the surface electromagnetic wave and exciton is the same as the effect of spatial dispersion on that of the system. For heavier exciton, the spatial dispersion has a little influence upon the property of the coupled system. The effect of lattice vibration on the dispersive property of the system is dominant. Whereas for the exciton with smaller effective mass, the effect of the spatial dispersion is dominant.
