A 20 Gbit/s directly modulated hybrid III-V/Si laser tunable over 12 wavelengths for short-reach access network
21 September 2014
We demonstrate a low cost tunable transmitter based on a directly modulated hybrid III-V/Si laser with enhanced modulation bandwidth. We successfully achieve 21.4 Gbit/s direct modulation including FEC overhead on 12 wavelengths over a short-reach access link (10-km).
