Abstract

The invention provides an optical receiving device and a manufacturing method thereof. The optical receiving device comprises a circuit board, a PD assembly, an SOA assembly, a bonding bridge sectionframe assembly and a gold wire group, wherein the PD assembly comprises a PD chip and a first lens group, and the SOA assembly comprises an SOA chip, a second lens group and a refrigerator; the bonding bridge section frame assembly is arranged between the circuit board and the SOA assembly; and the gold wire group is arranged at the upper part of the optical receiving device and is used for realizing electric connection between the SOA assembly and the circuit board; and incident light sequentially passes through the SOA chip, the second lens group and the first lens group and is transmitted to the PD chip, and the PD chip is configured to convert an optical signal into an electric signal. According to the optical receiving device provided by the invention, the SOA assembly is integrated to improve the information transmission distance, and meanwhile, the gold wire group is arranged in the upper space of the optical receiving device without changing the lateral size of the optical receiving device, so that the normal operation of a gold wire bonding process is not influenced, and the yield of the optical receiving device integrated with the SOA assembly is improved.

Description

technical field [0001] The present application relates to the technical field of optical communication, in particular to an optical receiving device and a manufacturing method thereof. Background technique [0002] In the light-receiving device, a PD (Photo Detector) component is usually used to photoelectrically convert the received incident light to convert the optical signal into an electrical signal. Generally, PD components can only meet the transmission requirements of 30km, and some PD components can barely meet the transmission requirements of 40km, but cannot meet the transmission requirements of 80km at all. [0003] In the prior art, some researchers integrate SOA (Semiconductor Optical Amplifier) ​​components into light receiving devices to amplify received light energy so that it can meet the transmission requirements of 40-80 km. However, after integrating the SOA component, the overall size of the light receiving device will be increased, which will cause cer...
