OPTICAL INTEGRATED ELEMENT, MANUFACTURING METHOD THEREOF, AND OPTICAL COMMUNICATION DEVICE
Document Type and Number:
Japanese Patent JP2017092262
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide an optical integrated element whose alignment accuracy of an optical waveguide in the height direction is improved when an optical function element and an optical semiconductor element are integrated.SOLUTION: An optical integrated element 3 comprises: an optical semiconductor element 1 comprising a first protrusion portion 5 including an active layer 4, and a first recess portion 6 extending from a surface side to a position deeper than the active layer 4; and an optical function element 2 comprising an optical waveguide including a core layer, and a second recess portion 9 where an end surface of the core layer is exposed at a side surface. The optical semiconductor element 1 and the optical function element 2 are integrated in a state in which the bottom surface of the first recess portion 6 is in contact with the surface of the optical function element 2, and the first protrusion portion 5 goes into the second recess portion 9 and the active layer 4 is optically connected with the core layer.SELECTED DRAWING: Figure 1
