Claim 0:
1. An array based free space optical (FSO) communication apparatus, comprising:
a plurality of optical receivers configured in an array to simultaneously receive a transmitted FSO communication signal for increased optical conversion gain, wherein each optical receiver comprises:
an amplifier; and
an optical detector electrically coupled with an input of the amplifier, the optical detector comprising an optical absorption layer positioned over a substrate, wherein the optical absorption layer comprises at least one of indium gallium arsenide (InGaAs), indium gallium nitride (InGaN), indium gallium antimonide (InGaSb), gallium arsenide (GaAs), gallium nitride (GaN), gallium antimonide (GaSb), gallium arsenide phosphide (GaAsP), and aluminum gallium nitride (AlGaN);

and
combiner circuitry having a plurality of inputs and a combiner output, wherein each input is electrically coupled with an output of each amplifier.
