Problems solved by technology

However, since the two optical coupling shells cover the light-emitting element and the light-receiving element, the planar optical waveguide usually needs to be thicker or a cushion layer is provided between the planar optical waveguide and the circuit board, such as the planar optical waveguide to be compatible with the two optical The coupling shell is used for optical coupling, which increases the volume of the optical communication device
In addition, the volume of the optical coupling housing is usually large, which also increases the volume of the optical communication device, which is not conducive to miniaturization

Abstract

An optical communication device comprises a circuit board, a light-emitting component, a light-receiving component and a planar light wave circuit. The circuit board comprises an installation surface. The installation surface is provided with a groove. The groove comprises a bottom surface, a connection installation surface as well a first inclined surface and a second inclined surface of the bottom surface. The first inclined surface and the second inclined surface are respectively provided with a reflecting layer. The light-emitting component comprises a light-emitting surface. A first light concentration portion is formed on the light-emitting surface. The light-emitting component is arranged on the installation surface and the first light concentration portion faces to the reflecting layer of the first inclined surface. The light-receiving component comprises a light-receiving surface. A second light concentration portion is formed on the light-receiving surface. The light-receiving component is arranged on the installation surface and the second light concentration portion faces to the reflecting layer of the second inclined surface. The planar light wave circuit is formed on the bottom surface, and the two ends of which are opposite to the reflecting layers of the first inclined surface and the reflecting layer of the second inclined surface respectively. The planar light wave circuit is formed on the bottom surface of the groove, so that the size of the optical communication device can be substantially reduced.

Description

technical field [0001] The present invention relates to the field of optical communication, in particular to an optical communication device. Background technique [0002] Existing optical communication devices generally include a circuit board, a light emitting element, a light receiving element, a planar light wave circuit (PLC) and two optical coupling housings. The light-emitting element and the light-receiving element are arranged on the circuit board at intervals. The planar optical waveguide is formed on the circuit board and arranged between the light-emitting element and the light-receiving element. Two optical coupling shells cover the light-emitting element and the light-receiving element respectively, one of which is coupled with one end of the light-emitting element and the planar optical waveguide, and the other optical coupling shell is coupled with the other end of the light-receiving element and the planar optical waveguide coupling. However, since the tw...
