Ridge waveguides were fabricated using the Er:BaTiO3 films doped with approximately 1 at.% Er. Pump/probe measurements showed stimulated emission resulted in a 2.4 dB reduction in the 1,540 nm absorption. It was concluded that to achieve net optical gain, the background losses need to be further reduced.

The microstructure of the $\rm BaTiO\sb3$ films was investigated. The surface roughness generally increased with thickness, and the films were composed of many small subgrains, 0.1 to 0.3 microns in diameter. Grain boundary grooving was responsible for the observed surface roughening. Deposition of the metalorganic precursor on the substrate prior to the initiation of growth also contributed greatly to the surface roughness.

Download Investigation of Ferroelectric Domain Structure and Nonlinear Optical Properties in Barium Titanate Epitaxial Thin Films Book in PDF, ePub and Kindle
The ferroelectric material barium titanate exhibits exceptional electro-optic and dielectric properties, making it desirable for electro-optic applications, especially in thin film form. The effective nonlinear optical and dielectric properties of BaTiO3 films are determined by the ferroelectric domain structure. The ferroelectric domain structures of epitaxial BaTiO3 films on MgO (100) substrates were investigated using x-ray diffraction (XRD), scanning probe microscopy (SPM), and second harmonic generation (SHG) techniques.

A simple gain model using the parameters determined in this study indicates Er doped BaTiO$\sb3$ is a promising optically active media if the losses can be sufficiently reduced.

Research on ferroelectricity and ferroelectric materials started in 1920 with the discovery by Valasek that the variation of spontaneous polarization in Rochelle salt with sign and magnitude of an applied electric field traced a complete and reproducible hysteresis loop. Activity in the field was sporadic until 1935, when Busch and co-workers announced the observation of similar behavior in potassium dihydrogen phosphate and related compounds. Progress thereafter continued at a modest level with the undertaking of some theoretical as well as further experimental studies. In 1944, von Hippel and co-workers discovered ferroelectricity in barium titanate. The technological importance of ceramic barium titanate and other perovskites led to an upsurge of interest, with many new ferroelectrics being identified in the following decade. By 1967, about 2000 papers on various aspects of ferroelectricity had been published. The bulk of this widely dispersed literature was concerned with the experimental measurement of dielectric, crystallographic, thermal, electromechanical, elastic, optical, and magnetic properties. A critical and excellently organized cpmpilation based on these data appeared in 1969 with the publica tion of Landolt-Bornstein, Volume 111/3. This superb tabulation gave instant access to the results in the literature on nearly 450 pure substances and solid solutions of ferroelectric and antiferroelectric materials. Continuing interest in ferroelectrics, spurred by the growing importance of electrooptic crystals, resulted in the publication of almost as many additional papers by the end of 1969 as had been surveyed in Landolt-Bornstein.

By browsing about 10 000 000 scientific articles of over 200 major journals mainly in a 'cover to cover approach' some 200 000 publications were selected. The extracted data is part of the following fundamental material research fields: crystal structures (S), phase diagrams (also called constitution) (C) and the comprehensive field of intrinsic physical properties (P). This work has been done systematically starting with the literature going back to 1900. The above mentioned research field codes (S, C, P) as well as the chemical systems investigated in each publication were included in the present work. The aim of the Inorganic Substances Bibliography is to provide researchers with a comprehensive compilation of all up to now published scientific publications on inorganic systems in only three handy volumes.
