Abstract
Claims
1. A light guide element comprising: a body; a beveled structure disposed on the body and protruding relative to the body; a barrier wall disposed around the beveled structure and protruding relative to the surface of the beveled structure; and a metal layer covering the surface of the beveled structure and the barrier wall.
2. The light guide element as claimed in claim 1, wherein the height of the barrier protruding from the surface of the sloped structure is greater than the thickness of the metal layer.
3. The light guide element as claimed in claim 1, wherein the barrier has a barrier wall surface adjacent to the surface of the inclined structure, and at least a portion of the barrier wall surface is not covered by the metal layer.
4. The light guide element as claimed in claim 1, wherein the barrier has a surface that faces the same direction as the surface of the inclined structure, the metal layer includes a first metal portion and a second metal portion that respectively cover the surface of the inclined structure and the surface of the barrier, and the first metal portion and the second metal portion are not connected.
5. The light guide element as claimed in claim 4, wherein the surface of the barrier is a smooth surface or a rough surface.
6. The light guide element as claimed in claim 1, wherein the barrier surrounds three sides of the inclined structure.
7. The light guide element as claimed in claim 1 further includes a connecting portion, wherein the connecting portion is disposed on the body and protrudes relative to the body, the connecting portion being used to connect an electronic component.
8. The light guide element as claimed in claim 7, wherein the connecting portion and the inclined structure are disposed on the same plane of the body.
9. The light guide element as claimed in claim 8, wherein the height of the protrusion of the connecting portion relative to the plane of the body is less than the height of the protrusion of the beveled structure.
10. The light guide element as claimed in claim 7, wherein the metal layer is used to reflect light signals from the electronic element.
11. The light guide element as claimed in claim 1 further includes an arcuate portion, wherein the arcuate portion is disposed adjacent to the beveled structure on the body and protrudes relative to the body.
12. The light guide element as claimed in claim 1 further includes a wall, wherein the metal layer further covers the surface of the body, and the wall is disposed around the metal layer on the body and protrudes relative to the surface of the body.
13. The light guide element as claimed in claim 12, wherein the height of the enclosure protruding from the surface of the body is greater than the thickness of the metal layer.
14. The light guide element as claimed in claim 13, wherein the enclosure has a wall surface adjacent to the surface of the body, and at least a portion of the wall surface is not covered by the metal layer.
15. A semiconductor structure comprising: a photonic integrated circuit; and a light guiding element as described in any one of claims 1 to 6 and 11 to 14, wherein the light guiding element is disposed on the photonic integrated circuit and guides an optical signal transmitted by the photonic integrated circuit in a first direction toward a second direction, and the first direction is not parallel to the second direction.
16. A semiconductor structure comprising: a photonic integrated circuit; and a light guiding element as described in any one of claims 7 to 10, wherein the electronic element includes the photonic integrated circuit, the light guiding element is connected to the photonic integrated circuit via the connection portion, and the light guiding element guides an optical signal transmitted by the photonic integrated circuit in a first direction toward a second direction, wherein the first direction is not parallel to the second direction.
