      Dear friends
      hope you all will be fine
      i want to use DFB laser in my simulation but i am not finding DFB in laser component library.Please tell me how to get the same in optisystem.Also tell me what is the specialized use of DFB over CW laser or any other type of laser source?
      i will be highly obliged for your kind help
      regards

      You can find the DFB laser in the Transmitters Library\Optical Sources\ folder. It uses two models, the Transmission Line model being the most physically accurate.

      The major difference between a classical Fabry Perot cavity laser and a DFB is the use of a Bragg grating instead of two reflective mirrors. The Bragg grating is a much more selective cavity design and therefor the linewidth of the will be smaller then a comparable FP cavity laser.

      Sir D.Marek
      i am using optisystem v.7
      in transmitters and sources folder i am not finding the DFB laser rather there are CW laser,laser rate equation,laser measured,LED,While light LED,pumplaser and pump laser array,CW laser array,CW laser measured,Directly modulated laser,CW laser array ES,VCSEL,VCSEL array,controlled pump laser,spatial VCSEL etc
      what can be done in this matter…plz help
