Characteristics of optoelectronic feedback for smart pixels with smart illumination

The application of optoelectronic feedback in addressing various problems in smart pixel arrays is considered. Special attention is paid to issues associated with light sources such as device nonlinearity and nonuniformity. Moreover, new classes of smart pixel applications taking advantage of the useful properties of optoelectronic feedback are discussed. Experimental results from a demonstration chip based on monolithic integration of optoelectronic devices on GaAs substrate are presented.
