Abstract
Abstract An array of electro-optical units in the form of a unitary device is formed. A single electro-optical crystal, such as lithium, niobate, or its equivalent, has a number of parallel slots cut into the body of the crystal. Each slot is filled with an electrically conductive foil that is made to adhere to the walls of the slot using an electrically conductive adhesive. The foils extend beyond the boundaries of the crystal to serve as electrodes.
