ABSTRACT:
The present invention provides optical integrated circuits in which both a light function zone and a light reception zone are monolithically formed on the same substrate to obtain high reliability and low noise and loss. The optical integrated circuits according to the present invention have improved electrode structure formed on a light wave guide layer to apply a major portion of the electric field generated by the current flowing in the electrode structure within the light wave guide layer to thus improve light receiving sensitivity. Further, the optical integrated circuits according to the present invention have the light reception zone of the large photoconductive effect on the substrate to develop a light receiving sensitivity to the light function zone without affecting propagation loss.
