| Research Abstract |
We constructed a metallic air-gap planar microcavity of a prism/metal/dye layer/air gap/metal, which allowed exciations of enhanced evanescent waves. A small mechanical variation of the air-gap distance was sensitively detected with modulation of the interference of light through the air gap. The demonstration shows that the air-gap distance is controlled in submicron scale. Emission with spectra modulated by the air-gap distance could not be observed from the microcavity with dye molecules excited by light irradiation. On the other hand, we have found that photoluminescence spectra for organic thin films on metal depended remarkably on emission angles.
