Abstract
The present disclosure provides an optical fiber to silicon photonics circuit (PIC) assembly method utilizing a structured fiber retaining apparatus for fiber confinement in which polymer filling volume for adhesion and refractive index matching purpose is reduced. Reduction of polymer volume result in smaller optical alignment change due to polymer material volume changes upon moisture absorption and aging, hence improving assembly reliability. In an embodiment, the assembly method and apparatus, transparent polymer material interfaces between fiber and edged coupler volume reduce more than 50% compares to conventional assembly method.
