ABSTRACT:
The present invention provides an optical system that includes an array of opto-electronic devices, an array of micro lenses, and a fore optic. The array of opto-electronic devices lie substantially along a plane, but the fore optic has a non-planar focal field. To compensate for the non-planar focal field of the fore optic, each opto-electronic device has a corresponding micro lens. Each micro lens has a focal length and/or separation distance between it and it respective opto-electronic device, which compensates for the non-planar focal field of the fore optic. The focal lengths of these lenses may differ relative to one another. As a result, light that is provided by the fore optic is reconfigured by the micro lenses having various focal lengths to be substantially focused along the plane of the array of opto-electronic devices. Various arrangements of microlenses, placing lenses on standoffs or posts, forming of optical waveguides, lens fabrication, wafer integration of micro-optics, and optical coupling are noted.
