Abstract: PROBLEM TO BE SOLVED: To realize monolithic integration of an optical attenuator to enhance optical absorption efficiency by setting film thickness of a semiconductor layer of the same composition forming a multiplex quantum well structure used as the optical absorbing layer of a waveguide photo sensitive element and an optical attenuator thinner than that of the optical absorbing layer of the optical attenuator in comparison with the waveguide photosensitive element. SOLUTION: A thick MQW layer is formed in the area to form a waveguide photosensitive element 20 and a thinner MQW layer is formed in the area to form an attenuator 30. A thin MQW layer is formed in the area to form HBT 40 isolated by the predetermined distance from the waveguide photosensitive element 20. The MQW layer in the thick region is used as the i-MQW optical absorbing layer 23 of the waveguide photosensitive element and the MQW layer in the area in which the thickness changes is used as the i-MQW optical absorbing layer 33 of the optical attenuator 30. The MQW layer in the thinner area is used as the i-MQW collector layer 43 of HBT 40.
