Abstract

The invention provides an optical receiving module and an optical communication device, and relates to the field of optical signal processing technology. The optical receiving module comprises: a first substrate; an array waveguide grating arranged on the surface of the first substrate, wherein a V-shaped groove is formed in one side of the array waveguide grating away from the first substrate; and a photoelectric detector, wherein the photoelectric detector is arranged on one side of the array waveguide grating away from the first substrate and opposite to the V-shaped groove to reduce lightsignals output from the V-shaped groove and convert the light signals into electric signals. As the V-shaped groove is formed in the array waveguide grating, the problem that an inclined plane needs to be cut on the output end of the array waveguide grating to reflect the light signals to the photoelectric detector, resulting in edge breakage of the output end of the array waveguide grating in related art, is solved.

Description

technical field [0001] The present invention relates to the technical field of optical signal processing, in particular to an optical receiving module and an optical communication device. 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 the optical receiving module including wavelength division multiplexing technology, according to the different devices for wavelength division multiplexing, it generally includes multilayer thin film technology and arrayed waveguide grating technology. Among them, arrayed waveguide grating technology is widely used due to its advantages of small waveguide size and high-density packaging structure. ...
