Influence of the sample structure on the corona type poling efficiency of guest-host electro-optic polymers

SECTION 6: OPTICAL COMMUNICATIONS (OC) [06.09]International audienceDuring the last decades, the research for the development of optical devices based on polymers is very extensive. Those organic materials make possible low manufacturing cost and high performance microwave photonic devices, such as optical modulators, with very large bandwidth and low drive voltage at 1310 nm and 1550 nm. To generate and maximize the electro-optic effect in those materials, it is necessary to orient all the chromophore dipoles in the same direction. In this paper, wire-to-plane configuration for corona poling and in-situ second harmonic generation detection techniques are used respectively to induce and to detect the alignment of the chromophores in a guest-host system (APC-CPO1). We report on experimental results obtained for various sample structures under same poling conditions. The sample structure affects the intensity of the corona current and its influence on poling efficiency has been studied through in-situ measurement of SHG (Second Harmonic Generation)
