Abstract

The invention provides an optical circulator assembly with a wavelength division function. The optical circulator assembly comprises a circulator core assembly and a wavelength division assembly, the circulator core assembly comprises a first PBS prism and a second PBS prism, and a non-reciprocal optical rotation part is arranged between the first PBS prism and the second PBS prism; and the wave division assembly comprises a substrate, a light inlet is formed in the side, adjacent to the second PBS prism, of the substrate, at least two optical filters for light with specific wavelengths to penetrate through are arranged on the other side of the substrate, a reflecting film for reflecting light which does not penetrate through the optical filters and is reflected by the light filters is arranged on one side of the substrate, and reflection sheets used for reflecting light to one side of the substrate are arranged between the adjacent optical filters. Compared with the prior art, the optical circulator assembly is a free space type assembly which is formed by connecting the circulator core assembly and the wavelength division multiplexing assembly into a whole, has no optical fiber input and output at two ends and is unrelated to polarization; and the coupling loss is reduced, the size is smaller, the performance is better, the cost is lower, and the device can be packaged at various positions in the device.

Description

technical field [0001] The invention relates to the field of optical communication, in particular to an optical ring component with wavelength division function. Background technique [0002] like figure 1 As shown, the existing two-channel wavelength division technology solution includes an independent online three-port optical circulator 1, an independent online three-port optical wavelength division multiplexer 2 (online means that there are optical fiber input and output at both ends), The three ports 13 of the circulator are connected with the COM end of the wavelength division multiplexer through an optical fiber to form an optical circulator assembly with a function of splitting light according to the wavelength. When the light is input from the first port 11 of the circulator, it is output from the second port 12, When the light is input from the second port 12 of the circulator, it is output from the three-port 13, and the light output by the three-port 13 will ent...
