Directly modulated lasers monolithically integrated with an optical filter for long range access network

The future access networks requires to develop key innovative transmitters operating at 10Gb/s around 1550nm and capable of transmitting data in extended reach passive optical networks (>60km). In this contribution, we demonstrate a novel cost-effective transmitter based on the monolithic integration on InP substrate of a directly modulated laser and a ring resonator compatible with the NGPON2 requirements.
