TL;DR: A novel investigation on the enhancement of phase noise in coherent optical transmission system due to electronic chromatic dispersion compensation is presented and the performance of differential QPSK demodulation system is compared.

TL;DR: In this article, a 116 Gb/s on-off keying (OOK), four PAM and 8 PAM optical transmitter using an InP-based integrated and packaged externally modulated laser for high-speed optical interconnects with up to 30dB static extinction ratio and over 100-GHz 3dB bandwidth with 2 dB ripple.

TL;DR: It is found that equalization enhanced phase noise--which appears as correlated pure phase noise, amplitude noise and time jitter-cannot be efficiently mitigated by the use of an (optically or electrically generated) RF pilot tone.

TL;DR: A detailed study comparing two filters for the CD compensation namely the fixed frequency domain equalizer (FDE) filter and the adaptive least-mean-square (LMS) filter provides important novel physical insight into the equalization enhanced phase noise (EEPN) influence on the system bit-error-rate versus optical signal-to-noise-ratio (OSNR) performance.

TL;DR: An adaptive finite impulse response filter employing normalized least mean square algorithm for signal equalization is developed for compensating the chromatic dispersion in a 112-Gbit/s polarization division multiplexed quadrature phase shift keying coherent communication system, which is established in the VPI simulation platform.
