Patent ID: 6927382

Claim:
An optical excitation/detection device, comprising: a CMOS fabricated photodetector array including a plurality of individual CMOS integrated photoreceptors, said CMOS integrated photoreceptors are not a deposited circuit block on said CMOS fabricated photodetector array, the array having a top surface into which is formed, between the CMOS integrated photoreceptors, a plurality of recessed regions having a certain geometric profile, each of the recessed regions being for receiving a photoemitter semiconductor block; and a plurality of separate photoemitter semiconductor blocks each said photoemitter semiconductor block comprising a photoemitter and each having a certain geometric profile that is complementary in size and shape to the certain geometric profile of the recessed regions, the separate photoemitter semiconductor blocks being deposited to fit within the plurality of recessed regions in the CMOS fabricated photodetector array, wherein only the photoemitter semiconductor blocks are deposited in the recessed regions.
