Smart pixel sensor arrays based on optoelectronic feedback

Summary form only given. Smart pixels present the possibility of integrating an array of light detectors and an array of light sources on a single chip. The demonstration chip used for experiments was based on monolithic integration of LEDs and optical detectors and was fabricated as part of MIT´s OPTOCHIP project. Each pixel in our design included a LED in the middle, and a pair of MSM and OPFET detectors. These results demonstrate the validity of the model for integrated LED sources and provide a base for implementation of more advanced sensor systems.
