Abstract

An external field applied to dye doped polymers which have inhomogeneous dispersion in their absorption spectra causes a shift in the absorption of the dye molecules. This, in turn, changes the line shapes of persistent spectral holes¹⁾. The Stark effect has been applied to optical storage²⁾ and optical computing³⁾. It has been also used as a powerful tool for investigating such physical profiles of materials as the difference between the effective molecular electric dipole moments in the host matrix in the ground and excited states which is related to hole burning^4),5).
