Description
Summary:A 32 /spl times/ 32 element InGaAs focal plane array was demonstrated. These arrays may find application in 3-dimensional imaging systems. APD arrays will be advantageous in these systems since the bandwidths required of the readout integrated circuits push their noise performance into the regime where avalanche photodiodes are useful. Further work is underway on both readout integrated circuits for the arrays, as well as integrated microlenses that will improve the fill-factor of the arrays.
