Dear Aabid Baba,

Thanks for your input. I have understood the implementation of phase locked loop for electrical systems. The point is here is PLL with optical system using optiwave. For this two things are required
1. Feedback environment in optiwave tool : This is now pretty clear for me, thanks to electrical pll link shared by you all.
2. Tunable laser simulation in optiwave: Optiwave library doesn’t have this component. Thus, this problem is still open. I am looking for – whether I can simulate tunable laser wherein electrical voltage will control the optical wavelength of laser source. Requesting help in this.

Dear Karan,
I understand advantages and implementation of tunable laser source. But problem here is simulation in optiwave. Optiwave doesn’t have the tunable laser component in library. I am looking at alternate ways to simulate this.

Dear All,
Thanks for sharing this information. This is helpful to tackle feedback problem. Thanks a lot.
In case of optical Phase locked loop, I require Tunable laser (Local Oscillator) which is equivalent to VCO in electrical PLL.
Does anyone has reference on tunable laser (say tunable range of ~ 500 pm) in optiwave software?

Thanks !!!
