Abstract:
1. A semiconductor package, comprising: an optically transmissive material that comprises a thermosetting polymer having a first refractive index; a first receptacle comprising a first portion of an optically opaque material having a second refractive index greater than the first refractive index, wherein the first receptacle partially surrounds the optically transmissive material, and is adapted to secure an optical conductor in alignment over a portion of the optically transmissive material absent any optically opaque material immediately adjacent thereto; a first integrated circuit mounted to a first portion of a leadframe, both of which are at least partially surrounded by the optically transmissive material, wherein the portion of the optically transmissive material absent any optically opaque material immediately adjacent thereto comprises a lens, and wherein a surface of the first integrated circuit is spaced from a top surface of the lens by a focal length of the lens; a second optically transmissive material; and a second receptacle comprising a second portion of the optically opaque material partially surrounding the second optically transmissive material and adapted to secure a second optical conductor in alignment over a portion of the second optically transmissive material absent any optically opaque material immediately adjacent thereto.
