Paper Abstract

Fiber optic RF distribution of signals has many attractive features but can be problematic when the combining function of an array is attempted at optical frequencies. A photodiode array is described that permits the simultaneous detection of RF modulation in optical links and the combining of the resultant RF signals in a coherent fashion. A small photodiode array was built and tested in a phased array to demonstrate beam formation.
