Abstract

An optical module device includes a substrate, an optical detector, and an optical demultiplexer. The optical detector is disposed on the substrate for detecting a light signal and generating a corresponding electrical signal, the optical detector having a detector surface. The optical demultiplexer is provided with a body, the body is provided with a multiplexer surface and faces the detector surface, the body is provided with a groove in the multiplexer surface, the groove is used for containing glue, the optical demultiplexer is bonded with the optical detector through the glue, and the detector surface is in direct contact with the multiplexer surface. According to the embodiment of the invention, the distance between the optical demultiplexer and the optical detector is reduced, so that the problem of power loss caused by light spot generation and optical path difference loss is solved.

Description

technical field [0001] The invention relates to an optical module device, in particular to an optical module device for receiving optical signals. Background technique [0002] Optical transceivers are used to transmit and receive optical signals for various applications, including Internet data centers, cable television broadband, and fiber to the home (FTTH) applications, among others. An optical transceiver may include one or more optical transmitting assemblies (transmitter optical subassemblies, TOSA) and optical receiving assemblies (receiver optical subassemblies, ROSA) for transmitting and receiving optical signals. In the optical receiving component, when the optical signal is transmitted from the optical demultiplexer to the optical detector, the generation of light spots and the power loss caused by the optical path difference must be considered. Contents of the invention [0003] In view of this, in one embodiment of the present invention, by reducing the dist...
