Abstract:
A method for manufacturing an electro-optic waveguide segment having a core and a cladding; the method comprising the steps of:removing a first selective portion of said cladding to form a first recess within said cladding, the first recessed cladding region having an outer dimension which is less than an unmodified section of said cladding;depositing a first electrically conductive material within said first recess by vapor deposition or sputtering and in direct contact with a bottom of said first recess, thereby forming a first electrode;placing said waveguide segment on a second electrically conductive material; said first and second electrically conductive materials not being in direct contact; andpoling said waveguide segment using at least a electric field applied to said first electrode to induce a non-linearity in said waveguide segment.
