Abstract
An optical element consists of an LN or LT crystal doped with MgO or ZnO. A +z surface and a -z surface of the crystal are connected to each other by means of a metal jig and an indium sheet. The +z surface and the -z surface may also be connected to each other by means of an electrically conductive wire material. The optical element may be a bulk crystal, an optical waveguide type electro-optical modulator, or a bifurcated interference type optical modulator. In this way, an optical damage resistant property of the optical element is improved.
