Abstract
An optoelectronic coupling system includes an optoelectronic chip mounted on a substrate, having one or more optoelectronic components. A lower lens array is positioned over the optoelectronic chip and has a lower surface with a first portion at a first height to mount on the substrate and a second portion at a second height, higher than the first height, to accommodate a height of the optoelectronic chip. The lower lens array has an upper surface that comprises one or more lower lenses positioned over respective optoelectronic components of the one or more optoelectronic components. An upper lens array is positioned over the lower lens array and has one or more upper lenses positioned over respective lower lenses.

An optoelectronic coupling system, comprising:
- an optoelectronic chip mounted on a substrate, the optoelectronic chip comprising one or more optoelectronic components;
- a lower lens array positioned over the optoelectronic chip having a lower surface that comprises a first portion at a first height to mount on the substrate and a second portion at a second height, higher than the first height, to accommodate a height of the optoelectronic chip and having an upper surface that comprises one or more lower lenses positioned over respective optoelectronic components of the one or more optoelectronic components;
- and
- an upper lens array positioned over the lower lens array comprising one or more upper lenses positioned over respective lower lenses.
An optoelectronic coupling system, comprising:
- an optoelectronic chip mounted on a substrate, the optoelectronic chip comprising one or more optoelectronic components;
- a lower lens array positioned over the optoelectronic chip having an upper surface that comprises one or more lower lenses positioned over respective optoelectronic components of the one or more optoelectronic components;
- and
- an upper lens array positioned over the lower lens array comprising one or more upper lenses positioned over respective lower lenses, wherein a light path between the one or more optoelectronic components and the waveguide passes through a free-space cavity between the upper and lower lenses.
An optoelectronic coupling system, comprising:
- an optoelectronic chip mounted on a substrate, the optoelectronic chip comprising one or more optoelectronic components;
- a lower lens array positioned over the optoelectronic chip having an upper surface that comprises one or more lower lenses formed in a lower lens cavity of the lower lens array and positioned over respective optoelectronic components of the one or more optoelectronic components;
- and
- an upper lens array positioned over the lower lens array comprising one or more upper lenses formed in an upper lens cavity of the upper lens array and positioned over respective lower lenses.
