Abstract:

The Kramers-Kronig (KK) receiver has recently drawn a great deal of attention due to its capability to recover the full electrical field from the intensity waveforms and to detect the optical single-sideband signal directly without suffering from the signal-signal beat interference. In this presentation, I will discuss a couple of issues hindering the practicality of KK receiver. For example, digital upsampling required to accommodate the nonlinear operations in the KK algorithm increases the complexity and power consumption of digital signal processing at the KK receiver. Another issue is the estimation of DC component lost upon the AC-coupled photo-detection. Besides, practical considerations on the measurement of the carrier-to-signal power ratio will be discussed. I will present a couple of techniques to remedy these issues in this talk.
