Abstract

Second-harmonic microscopy has been successfully applied to characterize the second-order nonlinear layer in optical fibers thermally poled at 280 °C and 3.5 kV for 30 min. The nonlinear layer was found to be $\sim 5.1\mu \mathrm{m}$ deep under the anode and was not always centered about the closest point between the electrodes.
