Abstract
A photonics packaging method is provided. The photonics packaging method includes providing a substrate () and attaching a first optical device () to the substrate (). The first optical device () includes a first mode converter () optically coupled to a first integrated photonics chip (). A second optical device () is also attached to the substrate (). The second optical device () includes a second mode converter () optically coupled to a second integrated photonics chip (). The second optical device () is of a greater height than the first optical device (). An index-matching material () is disposed in a space between the first and second optical devices () and () and a force is applied on the second optical device () to cause the second optical mode converter () to align with the first optical mode converter (). The index-matching material () is subsequently cured.
