Electric-field thermally poled optical fibres for quasi-phase-matched second harmonic generation
Kazansky, P.G. and Pruneri, V. (1997) Electric-field thermally poled optical fibres for quasi-phase-matched second harmonic generation. IEEE Photonics Technology Letters, 9, (2), 185-187. (doi:10.1109/68.553085).
We report on quasi-phase-matched frequency doubling to the blue in electric-field poled optical fibres. An increase of a factor of ~10 in the conversion efficiency in comparison with the previous results is obtained. Our experiments show that the structure of the induced nonlinear grating is not uniform, both longitudinally and transversely. For this reason the value of the effective nonlinear coefficient is still far from the optimum expected from the measured value, through Maker's oscillation, for a uniformly poled fibre.
