introduction of time delay or optical delay

[Shubhankar Mishra]

Hey, actually I wanted to introduce an optical delay in one of my paths of consideration but the output is always null. I want the signal to reach the port after a prescribed time of my original signal.i tried introducing a time delay but as I’m viewing both the original signal and the delayed signal in different oscilloscope after the PD, they have the same value at every instant. I can’t view them simultaneously as well.For example I need the delayed signal to reach out after 5ns or so.
Please let me know if anything is available regarding it

Hi Mishra,
I have created a simple project (attached) for you that have two Guassian pulses shifted by a delay component. I introduced the relative delay as a variable (sweep) from -0.05 ns to +0.05 ns. Pls run it and note how the two pulses appears in each time delay value.
you are free to use it in your design.

thanks
