Title:
ARRAY-TYPE OPTICAL AMPLIFICATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/020288
Kind Code:
A1
Abstract:
An array-type optical amplification device, wherein a first lens array (202) collimates multiple first optical signals input from a first optical fiber array (201); a multiplexing unit (203) may multiplex the multiple collimated first optical signals with multiple paths of pump light, so as to superimpose same into multiple second optical signals; a third lens array (2042) may couple the multiple second optical signals into multiple doped optical fibers (2041); the multiple doped optical fibers (2041) provide a gain for the first optical signals in the multiple second optical signals; a fourth lens array (2043) collimates the multiple second optical signals output from the multiple doped optical fibers (2041); and a second lens array (205) couples, into a second optical fiber array (206), the multiple first optical signals that have obtained the gain, such that the multiple first optical signals that have obtained the gain are transmitted in the second optical fiber array (206) and are output.
