Electro-optically controlled beam deflection for grazing incidence geometry on a domain-engineered interface in LiNbO3

Electro-optically controlled beam deflection for grazing incidence geometry on a domain-engineered interface in LiNbO3
We report an analysis on the electro-optically induced beam deflection experienced by light traversing an interface between two anti-parallel domains in a sample of LiNbO3. In contrast to other work on prism deflection schemes, we present a grazing incidence geometry for light at incidence angles between 87.7° and 89.0° that has been investigated to maximise the deflection angles achievable. Further improvements can be obtained for both range of angular deflection and transmission uniformity, by faceting the exit face of the device at an optimum angle. We present a theoretical analysis for this configuration and compare with data obtained for a wavelength of 1.52 µm. A practical geometry would permit a deflection of ~140 mrad for an applied voltage of 1 kV.

Abstract

We report an analysis on the electro-optically induced beam deflection experienced by light traversing an interface between two anti-parallel domains in a sample of LiNbO3. In contrast to other work on prism deflection schemes, we present a grazing incidence geometry for light at incidence angles between 87.7° and 89.0° that has been investigated to maximise the deflection angles achievable. Further improvements can be obtained for both range of angular deflection and transmission uniformity, by faceting the exit face of the device at an optimum angle. We present a theoretical analysis for this configuration and compare with data obtained for a wavelength of 1.52 µm. A practical geometry would permit a deflection of ~140 mrad for an applied voltage of 1 kV.
