    • 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.
    • 光耦合装置包括光纤块,该光纤块包括与第一块部分的一侧接触的第一块部分和第二块部分,穿过光纤块的光纤,并且具有暴露在光学器件的底表面处的端面 光纤块,设置在光纤块下方的半导体芯片,并且具有设置在半导体芯片的顶表面上的光输入/输出元件,以对应于光纤的端面;以及平坦化层,设置在光纤的顶表面上 半导体芯片并具有凹部区域。 第一块部分的底表面具有比第二块部分更高的水平。 第二块部的底面与凹部的底部接触。 光纤与光输入/输出元件光学耦合。
