Widely-tunable electroabsorption-modulated sampled grating DBR laser integrated with semiconductor optical amplifier

摘要

Summary form only given. We have demonstrated a widely-tunable, 2.5 Gb/s transmitter based on a SG-DBR laser monolithically integrated with a SOA and electroabsorption modulator. Time-averaged powers in excess of 3 dBm and RF extinction ratio <10 dB across a 40 nm tuning range have been achieved. Error-free transmission at 2.5 Gb/s has been demonstrated for 200 km of standard single mode fiber.
