A coupling packaged silicon photonic chip

Abstract

The invention provides a coupled-packaged silicon photon chip comprising a substrate, a laser chip daughter board, a micro-optical module group, and a silicon photon chip. The laser chip daughter board and the micro-optical module group are respectively connected to the substrate. A groove for transmitting laser light is formed in one end, being close to the micro-optical module group, of the substrate. The laser chip daughter board is used for emitting a laser light wave; and the micro-optical module group is configured to convert the laser light wave into a TE wave and transmit the TE wave to the groove. The substrate is connected to the silicon photon chip; and an optical path coupling grating of the silicon photon chip is arranged at a TE wave transmission direction in the groove. Therefore, the back propagation of the interface light wave can be reduced to protect the laser chip; the low-loss coupling of the laser chip and the silicon photon chip is realized; the structure is compact and the size is small; the silicon-photon-wafer-level bonding packaging is realized; and the laser is outputted in a TE wave manner; and no mode converter needs to be manufactured on the silicon photonic wafer.
