The second-order non-linear optical susceptibility of thermally poled glasses, χ (2), should
be enhanced in proportion to the intrinsic third-order susceptibility χ (3), for a given frozen-in …

Per the rectification model of thermal poling, it has been proposed that intrinsic breakdown
strength plays a strong limiting role in the internal DC fields supported by the glass from the …

Glasses in a wide range of chemical composition were thermally poled and the stability of
the second-order optical nonlinearity induced was studied through isothermal annealing …

We show through numerical simulations and experimental data that a fast and simple
iterative loop known as the Fienup algorithm can be used to process the measured Maker …

Efficient thermal poling of electronically conducting glass is prevented by the inherent
difficulty to record a large electrostatic field within such glasses. To overcome this limitation …

An improved inverse Fourier transform Maker fringe MF technique is described to retrieve
the nonlinearity profile of thin films. It involves measuring the MF curve of two sandwich …

The mathematical details of a family of inverse Fourier transform techniques to uniquely
recover the second-order optical nonlinearity profile of thin films are discussed both …

A new nondestructive characterization technique, based on a modified Maker fringe
measurement, is reported that allows the complete determination of complex spatial …

Thermally poled fused silica glass was characterized with second-harmonic optical and
scanning electron microscopy. It was found that, along with the creation of a second-order …

Thermal poling is an attractive method to induce a nonlinear coefficient in silica materials.
We have investigated potential silica materials with respect to their suitability for thermal …
