OPTICAL INTEGRATED CIRCUIT DEVICE, FABRICATION METHOD OF THE SAME AND MODULE OF OPTICAL COMMUNICATION TRANSMISSION AND RECEIVING APPARATUS USING THE SAME

摘要

The present invention relates to an optical integrated circuit device, a fabrication method of the same and a module of an optical communication transmission and receiving apparatus using the same. The optical integrated circuit device comprises a semiconductor substrate, an active layer formed on an upper surface of the semiconductor substrate, a first current disconnection layer formed on an upper surface of the semiconductor substrate at both sides of the active later, a second current disconnection layer formed on an upper surface of the first current disconnection layer, and a convex portion formed on an upper portion of the active layer surface of the second current disconnection layer.
