Abstract

This paper describes a range of methods, developed at the University of Wales, that affect signal shaping for high bit rate optical communications. All the signal designs presented here aim to offer optimum performance in terms of receiver sensitivity for a broad range of system impairments and are also designed to be tolerant to variations in these impairments. This makes the filters ideally suited for use in system applications where the actual impairments cannot be accurately specified. The designs described here are particularly appropriate for systems dominated by signal dependent noise such as systems based on avalanche photodiodes, optically pre-amplified receivers and soliton systems. The circuits described here are all implemented as GaAs monolithic microwave integrated circuits (MMICs) to further enhance their applicability to systems that are planned for field deployment.
