1. A method for manufacturing an optical device, the method comprising:
forming a first layer of a first electrode material on a surface of a first substrate of the optical device;
disposing an electrically-conductive adhesive material on at least a region of the first layer corresponding to a first region of the surface of the first substrate;
ablating the disposed electrically-conductive adhesive material and the first electrode material on which the electrically-conductive adhesive material is disposed from at least one portion of the first region;
simultaneously ablating a remaining portion of the formed first layer of the first electrode material, separate from the first region, to create a first electrode;
forming a second layer of a second electrode material on a surface of a second substrate of the optical device;
ablating the formed second layer of the second electrode material to create a second electrode; and
forming a third layer of at least one active material between the first substrate and the second substrate, wherein the first electrode is disposed between the first substrate and said third layer of the at least one active material, and the second electrode is disposed between the second substrate and said third layer of the at least one active material.
