Abstract
An embedded optical fiber module is disclosed. The embedded optical fiber module is adapted to fit in a recess of a package substrate. The embedded optical fiber module is configured for optical signal transmission between different chips or electronic devices mounted on the package substrate.
Claims8
An embedded optical fiber module, comprising:
- a protection layer;
- a plurality of optical fibers embedded in the protection layer;
- and
- for each optical fiber of the plurality of optical fibers,
- a first reflection mirror on a first end of the optical fiber for reflecting incoming light into the optical fiber;
- and
- a second reflection mirror on a second end of the optical fiber for reflecting the light out of the optical fiber,
- wherein the first reflection mirror is a first isosceles right angle prism, and the second reflection mirror is a second isosceles right angle prism,
- wherein one of the isosceles side of the first isosceles right angle prism is exposed out of a top surface of the protection layer, one of the isosceles side of the second isosceles right angle prism is exposed out of the top surface of the protection layer, and
- wherein a side of each of the plurality of optical fibers is flush with the isosceles sides of the first and second isosceles right angle prisms which are exposed out of the top surface of the protection layer.

A package substrate, comprising:
- a plurality of metal pads on a top side of the package substrate, and configured to mount at least one chip thereon;
- a recess opened to the top side of the package substrate;
- a plurality of bottom metal pads on a bottom side of the package substrate, and configured to mount the package substrate onto a circuit board;
- and
- an embedded optical fiber module in the recess, the embedded optical fiber module comprising:
- a plurality of optical fibers;
- a protection layer wrapping the plurality of optical fibers;
- and
- for each optical fiber of the plurality of optical fibers,
- a first reflection mirror on a first end of optical fiber for reflecting incoming light into the optical fiber;
- and
- a second reflection mirror on a second end of the optical fiber for reflecting the light out of the optical fiber,
- wherein a side of each of the plurality of optical fibers is flush with surfaces of the first and second reflection mirrors which are exposed out of a top surface of the protection layer.
