Abstract

The capacity of optical memories can be enhanced by using extra dimensions to store the signals besides the spatial dimension. We have investigated the photochemical persistent hole burning (PHB) reaction in a series of quinone derivatives as the guest molecules. In wavelength dimension, we showed that 600 ultra-high multiple spectral holes can be recorded in a double layered system. To increase the multiplicity of spectral holes, we intended to use electric field as another dimension. We have investigated the influence of electric field effect (Stark effect) in the PHB reaction characteristics. We observed for the first time with the quinone derivative systems that the burnt holes were broadened and then diminished when the applied electric field was changed, and that they reappeared when the applied electric field was changed again to the initial value. Multiple hole formation in the electric field dimension and optical modulation by electric field were also achieved.
