Abstract :
We have first reported on a 94-channel wide-band WSL installed in a 22-pin butterfly package with a multi-wavelength locker. We could realize 40-nm operation in the L-band for an 8-DFB arrayed monolithic WSL by covering 5 nm per DF3-LD. By using a monolithically integrated WSL and minimizing the number of components on the wavelength locker we could install all function in a 12.7-mm × 20.8-mm standard butterfly package. This WSL module with a stable-wavelength operation and uniform locking performance is a promising development to provide a large degree of flexibility in DWDM system design.
