Y. Shizu and S. Komatsu: Crosstalk of Optical Switching Device Using Photorefractive Crystal and Interconnection Mask, Proc. SPIE, Vol. 3554 (1998) 140-143.

We experimentally examined the crosstalk of the switching device using BaTiO3 and interconnection mask. BaTiO3 is used to compensated the light loss by two wave mixing.
