4-channel /spl times/ 10-Gb/s operation of AlGaInAs-MQW-BH-DFB-LD array for 1-3-/spl mu/m CWDM systems

We have developed a 4-channel AlGaInAs MQW-BH-DFB-LD array for 1.3-/spl mu/m CWDM systems. High-speed characteristics up to a 10-Gb/s operation on all channels, and more than a 40-Gb/s throughput woe obtained at 85/spl deg/C.
