Sample orientation in corona-poled multilayer silica structures

摘要

The impact of sample orientation on the poling of single-sided multilayer silica structures is studied. The results show that the presence of a multilayer stack near the cathode creates a nonlinear region where it otherwise would not have formed. It is shown that field orientation impacts the location and magnitude of the induced nonlinearity. A nonlinearity is always present in the stack independent of whether the stack is on the anode or cathode side of the sample unlike the nonlinearity in bulk silica, which is always located on the anode side.
