Hi Gaganpreet,

I just reduced your lasers linewidths to 2 MHz for each without making ANY other change to any other part of your system, and now you can have the desired BER. Unless there is a mention of laser linewidth in your paper, you can set your transmitter laser and your CW laser linewidths (after the pump laser) to 2 MHz and this will prevent further bothering to make any other changes to your design. In many CW low power lasers, I have even seen lasers with much less linewidth than 2MHz, while in some cases for high power lasers, the linewidth is high. So you can even make the transmitter lasers’ linewidth even less and instead, increase the linewidth for your CW laser and get the good results. So please just check your paper for any value for linewidths.

Cheers!
