Abstract :
The authors demonstrate a novel electro-optically addressable switch that uses electric-field controllable total internal reflection at an interface between two anti-parallel domains fabricated in single crystal LiNbO3. With an applied field, the induced index change at the interface is sufficient to switch the beam from transmission to reflection with a contrast ratio exceeding 20 dB in current samples
