Description
Summary:The growing traffic demand in inter-data center and metro communications requires high-speed and low-cost transceivers that can flexibly adapt to different transmission distances of up to a few hundred km. Ultimately low-cost transceivers will use the simplest optical hardware: namely a directly-modulated transmitter and direct detection receiver. Using optical injection-locked directly-modulated lasers (OIL-DML), we propose a transmitter that can control the full field of the optical signal and achieve error-free transmission over up to 300 km of dispersion uncompensated SMF-28. We demonstrate such a transmission system and discuss its potential for short and medium reach communication systems.
