Abstract
A photoelectric conversion module includes a circuit board; a photoelectric conversion element mounted on a first main surface of the circuit board; and an optical lens provided in an optical path between an end surface of an optical fiber and the photoelectric conversion element, wherein a part of the optical lens is inserted in a recessed portion formed in the first main surface of the circuit board.
Claims15
A photoelectric conversion module comprising:
- a circuit board;
- a photoelectric conversion element mounted on a first main surface of the circuit board;
- and
- a spherical optical lens provided in an optical path between an end surface of an optical fiber and the photoelectric conversion element,
- wherein a part of the spherical optical lens is inserted in a recessed portion formed in the first main surface of the circuit board,
- wherein a diameter of the spherical optical lens is larger than an opening diameter of the recessed portion,
- wherein the photoelectric conversion element includes a bottom surface facing the first main surface of the circuit board and a top surface opposite the bottom surface,
- wherein the diameter of the spherical optical lens is greater than a length of a second main surface of the circuit board to the top surface of the photoelectric conversion element, and
- wherein the second main surface of the circuit board is on an opposite side of the first main surface of the circuit board.
