Title:
WAVELENGTH DIVISION MULTIPLEXING STRUCTURE
Document Type and Number:
WIPO Patent Application WO/2022/077680
Kind Code:
A1
Abstract:
A wavelength division multiplexing structure, comprising: a first reflective surface (301), a second reflective surface (302), a first optical filter (401), a second optical filter (402), and a preprocessing device; light incident on the first reflective surface (301) forms a C-shaped or approximately C-shaped first section of C-shaped optical path and enters the first optical filter (401), and light reflected by the second reflective surface (302) forms skew lines with incident light entering the first reflective surface (301); light incident of the preprocessing device forms a preprocessing optical path and enters the first optical filter (401), and the preprocessing optical path coincides with the optical path of light entering the first optical filter (401) from the second reflective surface (302) in the first section of C-shaped optical path; and light reflected by the first optical filter (401) is reflected by the second reflective surface (302), is reflected by the first reflective surface (301), and then forms a second section of C-shaped optical path and enters the second optical filter (402). A specific spatial optical path composed of a preprocessing device, two reflective surfaces and two optical filters is used to achieve a multiplexing and demultiplexing effect on beams, thereby having small volume, low insertion loss, and low cost, and a common port and other ports can be distributed on the same side or different sides.
