Abstract: Kramers-Kronig (KK) relation-based receiver can recover the field using a single-photodiode. However, the KK receiver requires a high carrier-to-signal power ratio (CSPR), and digital signal processing performed a few times faster than the Nyquist sampling… read more here.

Abstract: The Kramers-Kronig (KK) receiver is capable of retrieving the phase information of optical single-sideband (SSB) signal from the optical intensity when the optical signal satisfies the minimum phase condition. Thus, it is possible to direct-detect… read more here.

DOI: 10.1364/oe.526012
Abstract: As high-speed analog-to-digital converters (ADC) account for a significant portion of the receiver's cost in intensity-modulation (IM)/direct-detection (DD) systems, there have been substantial efforts to employ an ADC operating at a relatively low sampling rate.… read more here.
