Humidity effect on the decay of second-order nonlinearity in thermally poled fused silica.
Type I (GE124) and Type II (KV) fused silica were thermally poled in a vacuum and in air under identical poling conditions. Second-order nonlinear (SON) strength and nonlinear depth were found all to be the same. Samples were then stored in high and low humidity to study their SON stability. The SON of poled GE124 was stable over time despite different poling atmospheres and humidity in storage...
متن کاملDynamics of the second-order nonlinearity in thermally poled silica glass
We study the temporal evolution of both the second-order nonlinear coefficient and of the nonlinear thickness in thermally poled silica-glass slides by using a high-resolution all-optical technique. A time delay in the nonlinearity formation is observed, followed by an increase to a maximum, and a final decrease. The thickness is shown to increase at a rate that differs significantly from that ...
متن کاملElectric surface potential and frozen-in field measurements in thermally poled silica
Surface potential (SP) as well as nonlinear optical coefficients in thermally poled silica were measured and compared. It was found that the SP is directly related to the frozen-in voltage across the depletion layer. ©2007 Optical Society of America OCIS codes: 160.0160 Materials; 190.0190 Nonlinear optics
متن کاملThermally poled silica samples are structurally heterogeneous: Electron diffraction evidence of partial crystallization
Large structural modifications in v-SiO2 are found to be induced by ‘‘thermal poling,’’ a treatment which makes the glass act as a frequency doubler of an impinging infrared light. The electron diffraction patterns of poled silica plates reveal the presence of a large amount ~of order 10%! of crystallites showing patterns consistent with partial crystallization of the glassy matrix into the cri...
متن کاملCharacterization of thermally poled germanosilicate thin films.
We report measurements of the nonlinearity profile of thermally poled low-loss germanosilicate films deposited on fused-silica substrates by PECVD, of interest as potential electro-optic devices. The profiles of films grown and poled under various conditions all exhibit a sharp peak ~0.5 microm beneath the anode surface, followed by a weaker pedestal of approximately constant amplitude down to ...
