Performance of Kramers–Kronig Receivers in the Presence of Local Oscillator Relative Intensity Noise
2019
Journal of Lightwave Technology
There is increasing interest in low-complexity coherent optical transceivers for the use in short-reach fiber links. Amongst the simplest configurations is the heterodyne coherent receiver, using a 3-dB coupler to combine the signal with the local oscillator (LO) laser output, and a single photodiode for detection of each polarization. In this paper, through numerical simulations, we investigate the impact of signal-signal beating interference (SSBI) and LO relative intensity noise (RIN) on the
