Abstract

The embodiment of the invention provides a packaging method and a packaging structure thereof, and the packaging method comprises the steps: a plurality of optical devices are provided, each optical device is provided with an optical coupling port, and the optical coupling port comprises an input port and an output port; the input ports and the output ports of at least part of the optical devices in the plurality of optical devices are located on the same end face of the corresponding optical devices; performing physical layout on the plurality of optical devices, so that the input port and the output port of each optical device in the at least part of optical devices are optically coupled with the optical coupling ports of different optical devices respectively; the end faces, used for optical coupling, of the different optical devices are located in a coupling interface. The plurality of optical devices form at least one coupling interface; and carrying out coupling processing on the end surfaces of the optical devices on the two sides of the coupling interface.

Description

technical field [0001] The invention relates to the technical field of optical communication devices, in particular to a packaging method and a packaging structure thereof. Background technique [0002] In system-level design, there are usually multiple different optical devices that need to be connected. In a typical situation, two different optical devices need to be connected alternately. At this time, multiple coupling interfaces will be generated and multiple couplings will be performed. However, multiple couplings require repeated placing of the optical device on the bench and repeated coupling of the package. In this way, the coupling loss is increased, which affects the transmission quality of the optical communication link between the optical devices. Contents of the invention [0003] In order to solve related technical problems, an embodiment of the present invention proposes a packaging method and a packaging structure thereof. [0004] An embodiment of the p...
