Abstract
We demonstrate an eight-channel DFB array with 200 GHz spacing with excellent power (+/- 0.25 dB) and channel spacing uniformity (+/- 13 GHz). The laser array is fully integrated on silicon and suitable for high-volume, multiwavelength applications such as co-packaged optics or optical I/O.
