Ultra low power consumption operation of SOA assisted extended reach EADFB laser (AXEL)
We propose a novel structure to reduce the power consumption and extend the transmission distance of a 10-Gbit/s, 1.55-µm EADFB laser. The power consumption is reduced by 1/2 and the transmission distance is extended.
28-Gbit/s 80-km transmission using SOA-assisted extended-reach EADFB laser (AXEL)
We fabricated 1.3-pm AXELs to extend the transmission distance with 28-Gbit/s-NRZ signal. SOA-assisted gain is effective in increasing the average output power. We successfully demonstrated 80-km transmission with an APD-ROSA.
High performance uncooled C-band, 10 Gbit/s InGaAlAs MQW electroabsorption modulator integrated to semiconductor amplifier in laser-integrated modules
Long reach C-band 10 Gbit/s uncooled operation of laser integrated to InGaAlAs electroabsorption modulator packages is presented. Using a design employing InGaAlsAs multi-quantum wells (MQW), uncooled operation over an 80°C temperature range, with modulated output power in excess of 0 dBm, 1.7 dB maximum change in extinction ratio, and with a dispersion penalty of 1 dB for 1600 ps/nm propagation is demonstrated.
