| 摘要 |
An optical submount and a method of making the optical submount are described. A cavity is formed in a substrate. The cavity has sloping side walls. A photonics device is then mounted on the substrate at a predefined distance from the cavity with the optical axis of the photonics device aligned with a diagonal of the cavity. A spherical lens is seated in contact with the side walls of the cavity to have a predefined relationship with the photonics device without light beam obstruction.
