Optical coupling structure and manufacturing method therefor

Abstract

Disclosed are an optical coupling structure and a manufacturing method therefor. The optical coupling structure includes a first substrate, a plurality of light-source arrays disposed on a side of the first substrate, a second substrate, and a filtering layer disposed on a side of the second substrate. The first substrate is provided with a first through-hole penetrating through the first substrate, the first through-hole serves as a channel region and is preliminarily used for collecting optical signal emitted by each of the plurality of light-source array. The first substrate is disposed directly opposite to the filtering layer, the filtering layer is configured to filter light signals from different channel regions to reduce crosstalk of different wavelengths between adjacent channels. The second substrate is provided with a second through-hole to accommodate an end of an optical fiber, so that filtered optical signal may be transmitted to the fiber more accurately.

Dependencies are inferred from the claim text.
