I built the circuit for simulating the all-pass filter by using optocouplers. But I don't know why its frequency response differs so much from the same but with the resistors instead of the optocouplers.

I can't post it, because file's format is unallowed here. So I can post images:Welcome to AAC!
A quick scan of your .zip file shows no problems but you should know that most members, including me, will NOT open a .zip file due to security concerns. Please post files in their native format.
Good luck!
What if I don't have H11F1 in Proteus, can I interchange it with some another linear optocoupler? Or can I download a package for Proteus with it?Hello,
The PC817 optocoupler will not create a linear resistor.
Better use an optocoupler with a fet as output, like the H11F1.

Is there a way to download it still?Hello,
This page of mouser shows a list of fet output optocouplers.
