Free space optical communications (FSO) requires receivers with a wide field of view, large collection area and high bandwidth, as well as good rejection of unwanted ambient illumination. At present most of the optoelectronic components used in these systems are designed for fibre-optic systems and as such are not optimal for this application.Work at the Universities of Oxford, Cambridge, Huddersfield and Imperial College has produced receivers incorporating detectors and preamplifiers specifically optimised for FSO and these show performance beyond that available commercially available. In this paper we describe the design, fabrication and performance of these integrated components. Further, we describe how this performance might scale with further optimisation, and future directions for optical receiver design
