    • A free space optical receiver comprising a photodetector and a fiber bundle. The fiber bundle comprises a plurality of optical fibers splayed apart at one of their ends to receive free space optical energy from multiple directions. The splayed apart ends of the plurality of optical fibers may create a hemispherical shape. Each of the plurality of optical fibers has an acceptance cone for which it couples optical energy into the splayed end of the optical fiber. The acceptance cones of the splayed ends of the plurality of optical fibers may overlap to form an omnidirectional acceptance zone. The other, non-splayed ends of the plurality of optical fibers are communicatively coupled to the photodetector, which is positioned to receive the free space optical energy from the non-splayed ends of the plurality of optical fibers. An optical communication system including the free space optical receiver is also described.
