25-Gb/s transmission over 2.5-km SSMF by silicon MRR enhanced 1.55-μm III-V/SOI DML

Konferensbidrag (refereegranskat)abstract
- The use of a micro-ring resonator (MRR) to enhance the modulation extinction ratio and dispersion tolerance of a directly modulated laser (DML) is experimentally investigated with a bit rate of 25 Gb/s as proposed for the next generation data center communications. The investigated system combines a 11-GHz 1.55-m directly modulated hybrid III-V/SOI DFB laser realized by bonding III-V materials (InGaAlAs) on a silicon-on-insulator (SOI) wafer and a silicon MRR also fabricated on SOI. Such a transmitter enables error-free transmission (BER< 10 -9 )at 25 Gb/s data rate over 2.5-km SSMF without dispersion compensation nor forward error correction (FEC). As both laser and MRR are fabricated on the SOI platform, they could be combined into a single device with enhanced performance, thus providing a cost-effective transmitter for short reach applications.

- Real-time transmission of 14-GBd 4-PAM signal is demonstrated by combining a commercial 1.55-μm DML with a silicon MRR. BER below the HD-FEC threshold is measured after 26-km SSMF transmission without offline digital signal processing.

Setting the stage for 100GbE serial standard - The HECTO project
- 2010
-
Ingår i: World Telecommunications Congress 2010, WTC 2010. - : VDE Verlag GmbH. ; , s. 118-123
-
Konferensbidrag (refereegranskat)abstract
- The standard for 100GbE will be adopted in 2010, defining transmission via 4 x 25 Gbit/s. A solution employing 1 x 100 Gbit/s would be cheaper - if the appropriate integrated components were available. These components now have been developed in the project HECTO. The project is shortly described and the main results are presented: the achieved performance of the components itself and the achieved system performance in a field trial. The complete ETDM system with monolithically integrated transmitter and receiver modules featured BER performance below standard FEC threshold (2 - 10 -3 ) in a field-link transmission with 112 Gbit/s over 42 km standard single-mode fibre.
