Disclosed is an optical emission assembly including a body, an adapter, two light-emitting assemblies, a multiplexer and a converging lens. The body is provided with a first positioning groove, a second positioning groove, an accommodation groove, and a through hole. The accommodation groove communicates with the first and second positioning grooves and the through hole. A groove bottom of the first positioning groove communicates with a groove bottom of the second positioning groove. The adapter is connected to the body and disposed corresponding to the through hole. When the two light-emitting assemblies are installed in the first and second positioning grooves, each light-emitting chip of each light-emitting assembly emits beams towards the accommodation groove to make the multiplexer disposed at the bottom of the accommodation groove combine the beams into one beam. The converging lens is disposed in the through hole to converge the one beam on the adapter.

Optical emission assembly and optical module

Disclosed is an optical emission assembly including a heat dissipation base, an adapter, a light-emitting assembly, a multiplexer, a cooling chip, a converging lens, a housing, and a heat-conducting glue. The heat dissipation base includes a first heat dissipation plate and a second heat dissipation plate forming a T-shaped or an L-shaped structure. The light-emitting assembly and the multiplexer are disposed on the second heat dissipation plate. The multiplexer combines light beams emitted by light-emitting chips of the light-emitting assembly into one light beam, and then the one light beam enters the adapter through the converging lens. The cooling chip is disposed on the first heat dissipation plate. The heat dissipation base and the cooling chip are disposed in the housing, and the cooling chip corresponds to a through hole of the housing. The heat-conducting glue is filled in the through hole and between the cooling chip and the housing.

Disclosed is an optical module, including a circuit board, a thermally conductive substrate, a structural adhesive, a silicon photonic chip, a laser assembly, and a fiber array assembly coupled to the silicon photonic chip. The thermally conductive substrate includes a first surface, a second surface, and a first bearing seat, a second bearing seat and a third bearing seat disposed on the first surface and exposed from the opening of the circuit board. The area of the second surface is smaller than that of the first surface. Part of the first surface contacts the circuit board. The thermally conductive substrate is fixed to the circuit board by the structural adhesive. The silicon photonic chip is disposed on the first bearing seat, the laser assembly is disposed on the second bearing seat, and a joint of the fiber array assembly is disposed on the third bearing seat.

Optical module

Disclosed is an optical module, including a lower housing, an upper housing covering the lower housing, a circuit board, a first metal base, a second metal base, a silicon photonic chip, and a light emission module including a laser chip and an optical path assembly. The first metal base is disposed on one side of the upper housing. The second metal base is disposed on one side of the lower housing. The circuit board with a hollow region is disposed on the second metal base. The silicon photonic chip is disposed on the second metal base exposed from the hollow region. The laser chip is disposed on the first metal base. The optical path assembly is disposed on the first metal base and/or on the second metal base exposed from the hollow region, and guides a third optical signal emitted by the laser chip to the silicon photonic chip.

Disclosed are a co-packaged integrated optoelectronic module and a co-packaged optoelectronic switch chip. The co-packaged integrated optoelectronic module includes a carrier board, and an optoelectronic submodule, a slave microprocessor and a master microprocessor disposed on and electrically connected to the carrier board. In the optoelectronic submodule, a digital signal processing chip converts an electrical analog signal into an electrical digital signal, an optoelectronic signal analog conversion chip converts an optical analog signal into the electrical analog signal to the digital signal processing chip, and an optical transceiver chip receives and transmits the optical analog signal to the optoelectronic signal analog conversion chip. The slave microprocessor monitors operation of the optoelectronic submodule. The master microprocessor processes a low-speed digital signal transmitted from the co-packaged integrated optoelectronic module to the outside, monitors operation of the co-packaged integrated optoelectronic module, and performs initialization of the co-packaged integrated optoelectronic module.
