Document Type and Number:
WIPO Patent Application WO/2023/013348
Kind Code:
A1
Abstract:
This optical module comprises: a substrate; an optical element; an optical coupling module; and an adhesive. The substrate has a glass cloth therein. The optical element is mounted on the substrate. The optical coupling module is configured to be optically coupled to the optical element. The adhesive fixes the optical coupling module to the substrate. A cavity that is recessed from a first main surface of the substrate toward a second main surface of the substrate so as to have a bottom portion is formed in the substrate. At least a portion of the optical coupling module is housed in the cavity. The glass cloth has a protruding portion that protrudes from a lateral surface of the cavity to the inside of the cavity. The protruding portion penetrates into the adhesive located between the lateral surface and the optical coupling module.
