Abstract :
We have developed wavelength-selectable arrayed DFB lasers with an integrated MMI coupler and SOA for WDM systems. Arrayed DFB lasers having eight and sixteen channels of DFB lasers are fabricated. The good uniformity of the DFB lasers characteristics provides uniform threshold current with the standard deviation of 0.37 mA in the arrayed 16 DFB lasers. The lasing wavelength difference between each laser is set to 3 nm, which corresponds to wavelength tuning range with a 30-degree temperature change. Wavelength range as wide as 46.9 nm is achieved with the 16 DFB lasers with a temperature control of 30-degree
