description An optical coupling device comprises an optical fiber block including a first block part and a second block part contacting with one side of the first block part, an optical fiber penetrating the optical fiber block and having an end surface exposed at a bottom surface of the optical fiber block, a semiconductor chip disposed below the optical fiber block and having an optical input/output element disposed on a top surface of the semiconductor chip to correspond with the end surface of the optical fiber, and a planarization layer disposed on the top surface of the semiconductor chip and having a recess region. A bottom surface of the first block part has a higher level than that of the second block part. The bottom surface of the second block part contacts with a bottom of the recess region. The optical fiber is optically coupled with the optical input/output element.
