  Hello Everyone,
  
  I am doing my research in the generation of Optical frequency comb. I found a paper where they used nonlinear effect to enhance FWM by designing a fibers loop which connected with polarization beam splitter. I simulated that system in Optisystem but i didn’t get the same results as in the paper. Then I designed the loop using connector with the splitter. But there is no impact of the loop in the system. Would you please help me that how can i design the fiber loop which will have an impact on the system??
  
  I have attached both the .osd file. Please help me out. Thanks in advance.

  HELLO RIFAT NAZNEEN..
  
  Well as far as your query is concerned i dont have much knowledge but i can provide you with the link of the post where it has been discussed how to design a frequency comb.. in the link Damian has said that it is possible with optisystem software… You can use CW Laser Array combined with the Ideal Mux. Set the number of ports for each component to some value N representing the number of lines and set the linewidth to 0 MHz in the laser array to get the Dirac comb…

  i think same type problem is associated in above link, where diamain sir clearly told that it possible to form it in the optisystem

  hi rifat nazneen,
  
  one way to employ optical frequency comb by using cascade intensity modulator and phase modulator.
  
  You can also use CW Laser Array combined with the Ideal Mux. Set the number of ports for each component to some value N representing the number of lines and set the linewidth to 0 MHz in the laser array to get the Dirac comb.
  
  To measure phase noise, the quickest way is to use our OSA component.

  Thanks a lot to everyone for your valuable responses. After reading your responses I am quit clear that there are several processes to generate comb. But still i am interested to design fiber looping for optical comb generation. Would you please give me some suggestion or techniques that can be helpful for me to design the highly nonlinear fiber loop in Optisystem?

  Hi Rifat Nazneen
  
  I’ve been working on this problem for a quite long time, for my research I used a cascade of MZ modulators,
  I read a very good article about optical frequency comb generation techniques. find it in attachment and i hope it will clear your thoughts
  
  Best regards

  Hi Atul Sharma,
  
  Actually these dots appear when a comment is modified on the forum… It was evident on the other posts as well..
