Abstract

An improved method and resulting device 10 for fabricating an electro-optical modulator material. The technique includes providing a substrate 509, which has a top surface. A first layer of electrode material 501 is defined overlying the top surface. The method also includes applying a transfer sheet 400, having an electro-optical material 405, to the first layer of electrode material 501, where the electro-optical material is affixed to the first layer of electrode material. A step of removing (e.g., peeling) 801 the transfer sheet from the electro-optical material is included. The removing step leaves a substantial portion of the electro-optical modulator material intact and affixed to the first layer of electrode material. This method generally uses less steps and provides a higher quality element than pre-existing techniques.
