  • In this paper, an angle diversity wireless optical detector is realized that can receive the optical signal at an angle from 0 to 360 degrees. Eight photodiodes constitute an angle diversity receiver, and in order to reduce the voltage variation with the incident angle, the optical detector is stabilized with a digital potentiometer. In a stabilized state, the voltage variation is kept within 1/10 of maximum voltage. This configuration is very useful in constructing an omni-directional receiver in a wireless optical interconnection.
