Polymers incorporating photochromic molecules are promising materials for flexible optical switches and
optical data storage devices. A study on reversible photoswitching of azobenzene incorporated polydimethylsiloxane is
carried out using transmittance and UV-VIS absorption measurements. The influence of light intensity on the
photoswitching behavior is also investigated. The transmittance measurements are correlated with the change in the
intensity of the corresponding bands in the UV-VIS absorption spectra. It is shown that the photoswitching occurs
reversibly and that the switching time scale decreases with increase in intensity.
