【Abstract】 The azodye Ethyl Red (ER) doped polymer (PMMA) films were prepared by the sol-gel process and the spin-coating technology, the all-optical switching characteristics of the samples were measured. The experimental results demonstrate that in the room temperature and while the control beam is 8mW and the period is 0.66 ms, the response time of the switching of millisecond magnitude and the modulation depth above 40% are obtained by choosing the proper doping concentrations (2~6wt%) of the samples and using strong polar solvent (cyclohexanone), the maximal modulation depth of switch reaches 72%.更多还原
