ABSTRACT:
An micro-photonics module includes an optical component and a photonics device mounted on a single substrate. The substrate defines a rectilinear cavity with flat bottom and flat side. The photonics device mounted on the substrate at a predefined distance from the cavity defines an optical path aligned to cross the rectilinear cavity. The optical component with portion abutting the flat bottom, flat side, and locator surface, is aligned with the optical path by the flat bottom and flat side of rectilinear cavity. The substrate may also define pyramidal cavity formed into the substrate from a major surface of the substrate, a notch formed in the substrate from the major surface and the flat side of the rectilinear cavity, and a locator surface within the rectilinear cavity. A ball lens may be seated in contact with the substrate within the pyramidal cavity to have a predefined relationship with the photonics device. The notch allows light to pass unobstructed between the ball lens and the optical component.
