Electro-optical effect definition

In order to achieve an optimum contrast for special electro-optical effects nematic liquid crystals should have definite values of birefringence. In most cases matching of refractive indices can be achieved by mixing two or more single components. Therefore the birefringence as a function of the concentration is of special interest. 

The simple analysis presented above confirms that new formulations are required to produce stable, reliable products for field use. Practical system requirements, as defined by Mil Spec conformity and the use of standard fabrication and assembly processes, definitely require that a electro-optic polymer system with better thermal properties than thermoplastic acrylates be developed. That this is true for optical interconnection boards and modules is not surprising because of their complexity. It is perhaps remarkable that it remains true for even simple devices, such as a packaged, pigtailed traveling-wave modulator. The ultimate success of electro-optic polymers will be their use in cost-effective products that are used by systems designers. 

If we think of some of Faraday s most important experimental discoveries of electro-magnetic rotation, of electro-magnetic induction, of the magneto-optical effect and of diamagnetism, then his two laws of electro-chemistry stand out as his only statements of definitive quantitative relationships. It is then of great interest to understand why Faraday, in this case, chose to use quantitative methods in his experimental work.
