The invention provides a light receiving module and light module assembly, relating to the technical field of light signal focusing processing. The light receiving module includes a convergent lens, a photodetector, and a silicon lens located between the convergent lens and the photodetector. The light signal transmission distance between the silicon lens and the convergent lens is less than or equal to the focal length of the convergent lens, and the silicon lens is attached to the photodetector. the convergent lens converges the received light signals and sends the light signals to the silicon lens before focusing, the silicon lens converges the received light signals and then sends the light signals to the photodetector, and the photodetector is used for converting the received light signals into electrical signals. By setting the silicon lens, the problem that in a light receiving module in the prior art, the converted light signals are different to effectively match with the photodetector can be solved.
Description
technical field [0001] The invention relates to the technical field of optical signal focusing processing, in particular to an optical receiving module and an optical module assembly. Background technique [0002] With the deepening of signal diversification, people have higher and higher requirements for the transmission of audio, video and other information. In the field of communication, optical communication is widely used in various industries due to its characteristics of large transmission capacity, high security performance and good anti-interference performance. In existing optical communication, a large amount of information is generally carried in a beam of optical signal to increase the amount of information transmitted by the signal, and the transmission rate of the optical signal is increased by reducing the area of the photosensitive area of the photodetector. [0003] However, the increase in the amount of information will lead to an increase in the cros...
