Abstract
Embodiments of the invention are generally directed to electronic alignment of optical signals. An embodiment of an apparatus includes an array of photo sensors; a bus coupled with the array, the bus including detection circuitry for each photo sensor to generate a signal in response to the photo sensor receiving an optical signal; and a processing component to process a group of signals, the group of signals being signals generated by the detection circuitry for a subset of the photo sensors in response to the photo sensors receiving the optical signal, to generate an output signal.
