A novel method is introduced to fabricate DFB laser arrays based on sampled gratings. An eight channel DFB laser array has been successfully fabricated,which demonstrates the feasibility of the method. The threshold currents of the elements of the laser array are in the range between 30 mA and 40 mA.The optical output power of each laser channel is about 10 mW at an injection current of 100 mA.The average frequency space between each two neighbor channels is about 200 GHz which satisfies the ITU standard. This kind of DFB laser array will play an important role in modern optical fiber communication system as a wavelength-selectable light source |
