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 holes). The Stark effect has been applied to optical storage) and optical computing). 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. In this paper, we used an electric field modulation technique to measure the Stark effect on wide and shallow spectral holes. The technique enables us to detect weak Stark effects on spectral holes in dye doped Polymers using a weak electric field at about 6 K.
