Abstract
The present disclosure relates to an optical fiber positioning device and, more particularly, to an optical fiber positioning device and a method for attaching a fiber optic array to a photonic integrated circuit (PIC). The structure includes: a body having a first end and a second end; a dome shaped indicator provided on the body; a first positioning mark associated with the dome shaped indicator; and a second positioning mark under the first positioning mark and associated with the dome shaped indicator.

A structure comprising:
- a body comprising a first end and a second end and composed of a transparent material;
- a first dome shaped indicator provided on the first end of the body;
- a second dome shaped indicator provided on a second end of the body;
- a first positioning mark associated with the first dome shaped indicator and the second dome shaped indicator;
- and
- a second positioning mark under the first positioning mark of the first and second dome shaped indicators, the second positioning mark being smaller than the first positioning mark.
3 more elements
A photonics assembly comprising:
- a substrate comprising a plurality of grooves on an upper surface thereof;
- a fiber optical array comprising a plurality of fiber optics placed within the grooves located on the upper surface of the substrate;
- and
- an alignment tool over the plurality of fiber optics, the alignment tool comprising a body with a first dome shaped structure with upper and lower positioning marks and a second dome shaped structure with upper and lower positioning marks, the lower positioning marks being concentric with the upper position marks when the plurality of fiber optics are in alignment with a waveguide along six degrees of freedom.
