Silicon photonic optical transceiver module

Abstract

The invention discloses a silicon photonic optical transceiver module. The silicon photonic optical transceiver module comprises a circuit board and an optical component; the circuit board is arrangedin a hollow region, and the hollow region is used for accommodating the optical component; the circuit board is provided with a plurality of first bonding pads along the periphery of the hollow region; a plurality of second bonding pads are arranged at the edge of the optical component; and after the optical component and the circuit board are attached in a reverse mounting mode, the second bonding pads are attached to the corresponding first bonding pads so as to implement electrical connection. The electrical connection is established between the circuit board and the optical component by the first bonding pads and the second bonding pads, an electric signal connection path is short, a stray capacitance is small, high-frequency transmission loss is low, high-frequency characteristics are improved, and the problem of high-frequency inhibition caused by a gold-wire bonding wire currently can be effectively improved. Meanwhile, the optical component and the circuit board are attached in a reverse buckling mode, the design structure is compact, and the size of the silicon photonic optical transceiver module can be effectively reduced.

Problems solved by technology

However, at present, the optical module generally adopts the method of gold wire bonding, which often brings radio frequency crosstalk and affects the performance of the optical module.

On the other hand, more and more functions are integrated in the optical module, and more and more devices are included in the optical module, which increases the difficulty of miniaturization and packaging of the optical module.
