| Abstract: | The techniques of preparing the nonlinear directional coupler in polymer PMMA/DR1 film by photobleaching are studied in this paper. We find an easier way to obtain a required coupling length by controlling photobleaching time rather than by controlling the dimensions of the coupler. The transmittance of each arm is measured when the input pulse light energy changes in our experiment. The experimental results show that the coupling length will change with the intensity of input light due to optical nonlinearity of the polymer PMMA/DR1 at 1 064 nm. |
