Abstract

This chapter describes the fundamental understanding of the detection of optical signals using direct techniques. Coherent detection has been presented in Chapter 3. Optical preamplification at the input of the optical receivers is not treated here but considered from parts by parts inserted in other chapters. Noncoherent or direct detection (DD) techniques can now be found in several low-cost optical systems in access networks to deliver multi-Tbps to end users for the coming data center-centric (DCC) networks and ultrabroadband optical networks for the fifth generation (5G) wireless communications cloud-based networking. Further, these techniques can be found very popular in interdata center communications.
