Impact of local oscillator frequency noise on coherent optical systems with electronic dispersion compensation.
Aditya Kakkar,Richard Schatz,Xiaodan Pang,Jaime Rodrigo Navarro,Hadrien Louchet,Oskars Ozolins,Gunnar Jacobsen,Sergei Popov +7 more
TL;DR: A theoretical investigation of the equalization-enhanced phase noise (EEPN) and its mitigation is presented and it is shown that elimination of the frequency noise below a certain cut-off frequency significantly reduces the transmission penalty, even when frequency noise would otherwise cause an error floor.
Comprehensive Study of Equalization-Enhanced Phase Noise in Coherent Optical Systems
Aditya Kakkar,Navarro,Richard Schatz,Hadrien Louchet,Xiaodan Pang,Oskars Ozolins,Gunnar Jacobsen,Sergei Popov +7 more
TL;DR: In this paper, a thorough analysis of equalization-enhanced phase noise and its impact on the coherent optical system is presented, and closed-form expressions of necessary LO linewidth and/or mitigation bandwidth for a general system configuration and specified OSNR penalty are given.

Experimental Study of 1.55- $\mu$ m EML-Based Optical IM/DD PAM-4/8 Short Reach Systems
Xiaodan Pang,Oskars Ozolins,Simone Gaiarin,Aditya Kakkar,Jaime Rodrigo Navarro,Miguel Iglesias Olmedo,Richard Schatz,Aleksejs Udalcovs,Urban Westergren,Darko Zibar,Sergei Popov,Gunnar Jacobsen +11 more
TL;DR: In this article, the authors evaluate high-speed intensity modulation/direct detection (IM/DD) transmissions with a 1.55-μm broadband electro-absorption modulated laser and pulse amplitude modulations (PAM).

100 Gbaud 4PAM Link for High Speed Optical Interconnects
Oskars Ozolins,Xiaodan Pang,Aleksejs Udalcovs,Richard Schatz,Urban Westergren,Jaime Rodrigo Navarro,Aditya Kakkar,Fredrik Nordwall,Klaus M. Engenhardt,Jiajia Chen,Sergei Popov,Gunnar Jacobsen +11 more
TL;DR: This work demonstrates 100 Gbaud 4PAM transmission over 400 meters SMF with monolithically integrated 1550 nm DFB-TWEAM and evaluates its capabilities to enable two lanes 400 GbE client-side links for optical interconnects.
