The drift issue induces slow drifting of the optimum operating point for high efficiency or large nonlinearities in analog optical links, and requires complex control of the offset bias voltage for achieving high extinction ratio in digital optical links. We discuss and analyze the different sources of the drift in commercially LiNbO<sub>3</sub>(More)
Polyfuran constitutes polymer belong the conjugated systems which have been pointed out functionalized properties in the electronic and optic fields. In the present paper, experiment and theoretical analysis on Polyfuran with his oligomers have been reported. The interpretation of the infrared and Raman spectra of Polyfuran is presented. In order to discuss(More)
In this work, a combination of experimental and theoretical study of Polyfuran and its oligomers, in their neutral and doped states, was reported. The effect of chain length on optoelectronic properties was discussed using the Density Functional Theory (DFT). Since the opto-electronic properties of this kind of conducting polymers are governed by their band(More)
