ABSTRACT:
A method of attaching electrodes to optical substrates with embedded waveguides includes applying the electrode pattern to a separate superstrate from the electro-optic material containing the waveguide. This allows for the change of the index of refraction and/or the dipole moment of an electro-optic material using low voltages. In0 addition, the electrode superstrate can be detached from the waveguide substrate and repositioned and aligned to different waveguides. Removable electrodes add flexibility and increase yield by allowing the electrodes to be re-aligned to the waveguides when improper alignment occurs.
