An optical device and method for making the same is disclosed. The device includes having a circuit element that is located in an opaque enclosure. The circuit element includes a die having an optical integrated circuit mounted on a carrier. The carrier includes a plurality of conductors connected to the optical integrated circuit. The opaque enclosure has a transparent window therein. The carrier is positioned in the enclosure such that light entering the enclosure through the window illuminates the die. The enclosure further includes an aperture through which the conductors protrude from the enclosure. The enclosure is at least partially filled with a layer of optically transparent material that passes light utilized or generated by said optical integrated circuit. The enclosure can be preformed to a higher degree of precision than that obtainable on conventional packaging fabrication lines.

Optical integrated circuit package

An optical tracking assembly for an optical mouse includes a light source, an optical sensor chip, and an integral optics assembly. The integral optics assembly includes lenses and alignment features receiving the light source. The alignment features center the light source to the lenses and control a distance the light source is placed away from a navigation surface that reflects light onto the optical sensor chip. The lenses may include (1) collimating lenses for collimating light from the light source along a first optical axis to the navigation surface, and (2) imaging lenses for imaging reflected light from the navigation surface along a second optical axis to the optical sensor chip.
