For the first time, we have registered, studied, and modeled the Maxwell–Wagner effect in structures with a smooth gradient of charge carriers’ mobility. The Maxwell–Wagner charge, formed after applying a DC voltage to the gradient structure at room temperature, is distributed over the entire region of the gradient. The experiments were performed with slides of a soda‐lime glass subjected to sodium‐to‐potassium ion exchange, where the ions concentration gradient provides gradient of conductivity while dielectric permittivity stays the same. The electric field generated by the Maxwell–Wagner charge is concentrated in potassium‐enriched less conductive regions of the slide and is sufficiently high to induce the second order optical nonlinearity in the initially isotropic glass. The effect causes over 100‐fold increase in a second harmonic signal relative to the signal from the surface of a virgin glass. This phenomenon in graded‐concentration structures is perspective for characterizing interfacial charges, geometry of the gradient regions, and spatial distribution of electrical conductivity in micro‐ and optoelectronic semiconductor structures.

“…The SHG photoelectric effect can be created by precipitation of ceramic within glass network 12 or using the thermal poling method. [13][14][15] For the second method, amorphous materials such as glass will not have SHG nonlinear optical properties due to their macroscopic inversion symmetry. The thermal polling technique changes the structure at the surface of an amorphous material by applying a large voltage of up to thousands of volts at high temperature, allowing the atomic ions to rearrange and form local dipolar.…”

The existence of optical nonlinear properties in silver-oxide-doped and -undoped germanotellurite glasses by using thermal poling treatment was demonstrated and compared. The variation of second-order nonlinear optical characteristics with poling voltage and their stability with time were observed via the macroscopic second harmonic generation measurement. The study also includes the investigation of enhancement of the nonlinear property by thermally poling K[Nb 1/3 Te 2/3 ] 2 O 4.8 volume-distributed glass-ceramic composite in which the role of silver in ceramic component and the modified surface structure layer of the glass component would be further discussed.

“…Ultimately, thermal poling should be used for in-fiber SHG. In this work, however, optical poling [13,14] is used. Although the peak conversion efficiency of optical poling does not exceed a couple of percent, the technique is considerably simpler to implement since it relies on the creation of a self-organized grating [15] through the interaction of high-power radiation at 1064nm with the SH light at 532nm, requiring neither internal electrodes nor periodic UV exposure.…”

Abstract:Two fiber Raman probes are presented, one based on an optically-poled double-clad fiber and the second based on an opticallypoled double-clad fiber coupler respectively. Optical poling of the core of the fiber allows for the generation of enough 532nm light to perform Raman spectroscopy of a sample of dimethyl sulfoxide (DMSO), when illuminating the waveguide with 1064nm laser light. The Raman signal is collected in the inner cladding, from which it is retrieved with either a bulk dichroic mirror or a double-clad fiber coupler. The coupler allows for a substantial reduction of the fiber spectral background signal conveyed to the spectrometer. References and links1. R. L. McCreery, M. Fleischmann, and P.
