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 includes a planar optical waveguide, a circuit board, a light-emitting element and a light-receiving element. The circuit board includes a mounting surface. Both the light-emitting element and the light-receiving element are carried on the mounting surface, and both are electrically connected to the circuit board. The light emitting element includes a light emitting surface. The light receiving surface includes a light receiving surface. The planar optical waveguide is embedded in the circuit board, and the planar optical waveguide includes a first inclined surface inclined relative to the installation surface and a second inclined surface inclined relative to the installation surface. A first light guide hole and a second light guide hole are defined on the installation surface. The first slope communicates with the first light guide hole. The second slope communicates with the second light guide hole. The light-emitting surface is opposite to the first slope through the first light guide hole. The light receiving surface is opposite to the second slope through the second light guide hole. The optical communication device is small in size.

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...
