Abstract

A DFB-LD array-based wavelength selectable light source is described (WSL). The WSL is very promising for DWDM applications because of its fine wavelength tunability and stability and its simple tuning scheme. Also, the advanced simple fabrication process used to produce this device is an effective one. Further optimizations of device structure make this type of device a practical light source for DWDM transmission systems.
