Abstract :
The tunability feature of short-cavity vertical-cavity surface-emitting lasers in the C-minus band to provide low-power, cost-efficient, colourless, and legacy system compliant transmitters for future time and wavelength division multiplexed passive optical networks is investigated. For the first time, a report is presented on error-free performances across a 800 GHz tuning range with a potential aggregate upstream capacity of 80 Gbit/s over a system reach of at least 40 km and with a 1:64 split ratio.
