Abstract
An optical module includes a board including a first surface and a second surface, a light-receiving element mounted on the first surface of the board, a capacitor mounted on the first surface of the board and connected to the light-receiving element, an optical waveguide attached to the second surface of the board and configured to transmit light, and a housing that covers the board. A recess is formed in an area of the inner surface of the housing to face the capacitor.
Claims5
An optical module, comprising:
- a board including a first surface and a second surface;
- a light-receiving element mounted on the first surface of the board;
- at least one capacitor mounted on the first surface of the board and connected to the light-receiving element, the capacitor including a lower surface that is in contact with the first surface of the board and an upper surface that is opposite the lower surface;
- an optical waveguide attached to the second surface of the board and configured to transmit light;
- and
- a housing that covers the board, wherein
- a recess is formed in an area of an inner surface of the housing to face the capacitor;
- and
- a gap between a bottom of the recess and the upper surface of the capacitor is greater than a gap between the first surface of the board and the inner surface of the housing excluding the area where the recess is formed.
