Abstract:
A method for fabricating an electro-optic modulator material, said method comprising:providing a first transfer substrate comprising a top surface;forming an electro-optic material onto said top surface of said first transfer substrate to attach said electro-optic material to said first transfer material, said forming step creating an exposed electro-optic material surface having a planarity that ranges between about 0 (zero) microns and about 4 (four) microns;forming a second transfer substrate overlying said exposed electro-optic material surface, said second transfer substrate being attached to said electro-optic material at lower strength than said attachment of said first transfer substrate to said electro-optic material;wherein said second transfer substrate has a larger surface area than said exposed electro-optic material surface to define a protruding region of said second transfer substrate that protrudes outside an edge of said electro-optic material; andapplying a force to said protruding region to remove said second transfer substrate from said electro-optic material and leaving said electro-optic material substantially affixed to said first transfer material.
