ABSTRACT:
An Integrated Optics Chip with improved performance when exposed to rapidly changing temperature is disclosed. The optic chip or integrated optic chip or MIOC has a top surface, a +Z face and -Z face. The chip is formed from a crystal having a high electro-optic coefficient such as Lithium Niobate. For the purpose of orienting the components to the optic chip to be described, the +Z crystal axis extends outward from the +Z face. An input waveguide formed in the top surface of the chip and orthogonal to the +Z axis receives an optical signal from an input port, passes the signal via a waveguide network, to an output waveguide coupling the waveguide network to an output port. Metalization is applied to the top face of the optic chip to form at least a first and a second rail. The first and second rails are positioned to very closely straddle a portion of the input waveguide. A conductive bridge connects the first and second rails to prevent a charge differential from developing between the first and second rails.
