As shown in fig. 1 to 3, the present utility model provides a preferred embodiment of a combined integrated device of a polarization beam combiner 100 and a beam splitter 200.
A combined integrated device of a polarization beam combiner 100 and a beam splitter 200 includes the polarization beam combiner 100 and the beam splitter 200; the light output end of the polarization beam combiner 100 is attached to the light input end of the beam splitter 200.
Specifically, the polarization beam combiner 100 and the beam splitter 200 are two independent components, but the two components are directly attached, namely two end faces are attached, the light beams (11, 12) directly enter the beam splitter 200 after being combined by the polarization beam combiner 100, and then are split into two light beams (13, 14) through the beam splitter 200, one light beam is directly output, and the other light beam is output to the MPD monitor 300, so that the monitoring of the light beams is realized.
In one embodiment, the polarization beam combiner 100 has a square structure, the beam splitter 200 has a square structure, and an output end face of the polarization beam combiner 100 is attached to an input end face of the beam splitter 200. The polarization beam combiner 100 and the beam splitter 200 with square structures are arranged, so that the direct end surface lamination of the polarization beam combiner 100 and the beam splitter 200 is facilitated, namely, the output end surface of the polarization beam combiner 100 and the input end surface of the beam splitter 200 are laminated, so that other components are not required to be additionally added, the operation difficulty is reduced, the polarization beam combiner 100 and the beam splitter 200 are integrated, and when the polarization beam combiner is used, the integrated polarization beam combiner is directly adhered to the corresponding position without optical path coupling, the manufacturing difficulty is greatly reduced, the operation efficiency is improved, and the yield is improved; because no coupling is needed, various expensive equipment such as a power supply, a high-precision power meter, a fixture and the like are not needed, the production cost is greatly reduced; the material quantity is reduced, the line management is facilitated, and the polarization beam combiner 100 and the beam splitter 200 are integrally manufactured, so that 1 material is correspondingly reduced, and the line management is facilitated.
Preferably, the output end face of the polarization beam combiner 100 and the input end face of the beam splitter 200 are attached by glue. Meanwhile, the glue bonding must ensure the tightness of the polarization beam combiner 100 and the beam splitter 200, so as to avoid scattering of light caused by overlarge gap when the light passes between the two.
In one embodiment, the first input end face of the polarization beam combiner 100 is disposed parallel to the output end face of the polarization beam combiner 100, and the second input end face of the polarization beam combiner 100 is disposed perpendicular to the first input end face.

The first input end surface of the polarization beam combiner 100 is parallel to the output end surface of the polarization beam combiner 100, so that direct transmission of light beams is facilitated, and no additional reflection lens or refraction lens is required in the middle. Similarly, the first output end face of the beam splitter 200 is disposed parallel to the input end face of the beam splitter 200 for the same reason.
By arranging the second input end face of the polarization beam combiner 100 perpendicular to the first input end face and the second output end face of the beam splitter 200 perpendicular to the first output end face, overall compactness is achieved, the incident position of light is close to the arrangement, and the emergent position of light is also close to the arrangement, so that the combined integrated device is miniaturized. Meanwhile, the second output end surface of the beam splitter 200 and the second input end surface of the polarization beam combiner 100 are arranged in a coplanar manner, so that the flatness of the whole end surface is improved, and subsequent assembly and maintenance are facilitated.
In one embodiment, the beam splitter 200 splits at a ratio of 2:98. monitoring of the beam with a split ratio of 2 is achieved with the MPD monitor 300. Referring to fig. 3, the integrated device further includes an MPD monitor 300, where the MPD monitor 300 is attached to the second output end face of the beam splitter 200, and the beam splitting ratio of the second output end face to the first output end face is 2:98, implementing the design of MPD monitor 300.
